BUSTED! AT&T begins crackdown on iPhone jailbreakers using MyWi tethering

By | March 18, 2011, 7:20am PDT

Now that Apple is offering iPhone users a way to legitimately get WiFi tethering through using the new Personal Hotspot feature in iOS 4.3, it seems that AT&T has begun a clampdown on those running the MyWi app on jailbroken iPhone handsets.

[UPDATE: Think that the data allowance that comes with your data plan is yours to do with as you wish? Think again!]

Some MyWi users have been hit with text messages and emails.

Here’s an example of the text message:

“AT&T Free Msg: Did you know tethering your Smartphone to a computer requires a tethering plan? Pls call 888-860-6789 for details or visit att.com/dataplans.”

Here’s the follow-up email:

Dear [Customer],

We’ve noticed your service plan may need updating.

Many AT&T customers use their smartphones as a broadband connection for other devices, like laptops, netbooks or other smartphones- a practice commonly known as tethering. Tethering can be an efficient way for our customers to enjoy the benefits of AT&T’s mobile broadband network and use more than one device to stay in touch with important people and information. To take advantage of this feature, we require that in addition to a data plan, you also have a tethering plan.

Our records show that you use this capability, but are not subscribed to our tethering plan.

If you would like to continue tethering, please log into your account online at Cell Phones and Cell Phone Plans - Wireless from AT&T, or call us at 1-888-860-6789 Monday - Friday, 7 a.m. - 9 p.m. CST or Saturday, 8 a.m. - 7 p.m. CST, by March 27, 2011 to sign up for DataPro 4GB for Smartphone Tethering.
Here are details on the plan:

DataPro 4GB for Smartphone Tethering
• $45 per month
(this gives you 4GB in total, combining both your smartphone data plan for $25 and the tethering feature, $20)
• $10 per each additional GB thereafter, added automatically as needed
• Mobile Hotspot capabilities are included for compatible Smartphones

If we don’t hear from you, we’ll plan to automatically enroll you into DataPro 4GB afterMarch 27, 2011. The new plan - whether you sign up on your own or we automatically enroll you - will replace your current smartphone data plan, including if you are on an unlimited data plan.

If you discontinue tethering, no changes to your current plan will be required.

It’s easy to track your usage throughout the month so there are no bill surprises. For example, we send you free text messages when you reach 65, 90, and 100 percent of your plan’s threshold. If you would like to monitor your account more closely, go to www.att.com/dataplans to learn about other ways to track your data usage.

As a reminder, our smartphone data plans also include unlimited usage of Wi-Fi at no additional charge. AT&T smartphone customers can use Wi-Fi at home or on-the-go at any one of our more than 23,000 U.S. hotspots already included in your data plan.

Thank you for bringing your account up to date. We appreciate the opportunity to continue to serve your mobile broadband needs.

Sincerely,

AT&T

BUSTED!

Bottom line is that users who have enabled tethering on their iPhone sing any feature other than the Personal Hotspot feature are breaking AT&T’s terms of service, and now that AT&T has a plan, it’s trawling for users who are already using the service but not paying for it.

But how are they spotting MyWi users? Three possibilities:

  • Network saturation
  • User agent IDs
  • Excessive data usage

However AT&T is going about this, it’s clear that the company is taking its network back from those who it considers to be freeloading.

Any readers had similar messages from AT&T? Anyone not using a tethering solution had the finger pointed at them?

I called and the warned me. If they switch my unlimited plan I will take the $200 or so termination fee and skip a year more of payments because ATT only allows max 4G where T-Mobile allows 5G. I want at least 5G. I helped a friend purchase a Sensation cell phone at T-Mobile and was surprised when that phone offered a choice to download movies without jailbreaking where my iPhone 4 only allowed streaming.
Also could be via ttl since the PC-to-iPhone is an extra hop. Or (unlikely) deep packet inspection.
@Real World
My guess is that the NAT inside the iPhone uses different port ranges for internal and external(WiFi) connections. Very easy to sniff out then.

True! ..and iDevices are all hypertunneled!
Monarky Updated - 18th Mar 2011
@ne6d@... So basically they know a iphone is jailbroken, since it's not hypertunneled (encrypted to a single port routing of Apple's network)!
They all use single port forwarding via encrypted tunneling to Apple's Servers. Like MS Xbox 360's do for Xbox Live Garden Walled Tunnel. Apple Network operates like AOL and Compuserve did. When you think you are on the real internet, you are actually inside a glass fishbowl of encryption. Only seeing it as it's continually crawled and updated on massive cloud storage. When visiting the real web in real time, it's slower and without full interactive access disallowed in the Intranet Onramp Server. Full interaction is impossible for simple things like managing your YouTube channel or commenting even only by proxy!

This the main reason that despite javascript engine update their browser is slower than Android on 84% of the web!

Apple needs to jailbreak all of their devices and open up their network for many reasons. Chief among them is freedom to browse the the web full speed, like everyone does on Macs, PCs and... of course Android!

Although I use a Hypertunneling Service (pay for encrypted vpn) for work related web access, that should be my choice in my private life. Hypertunneling is very secure... but do you really need it to watch videos on YouTube while not really there or read and write email on web mail services? Plus.... A&T are mad they CAN'T penetrate your Apple hypertunneled network (unless they use packet sniffing your traffic and then they have to break your encrypted data to do that. They just want to be able to sell you their own services and Apps directly (coming soon like on Verizon, etc markets coming)!

Worst part for Apple's Closed Garden Walled Network of users is...... NO 700 mhz 4G until Apple at least gives you a choice! .....but still the best part is that wireless service providers are locked out of snooping you and selling you crap apps unless Apple allows it inside their Garden Walls!

Isn't it got busted recently because those whoever involved in giving that result in favor of Google were doing it for personal reasons?

None of their business
Economister 18th Mar 2011
If I pay for a certain amount of data usage per month, it is none of AT&T's business how I use it.

It reminds me of the old cable company efforts to extract full monthly fees for every TV in your house. They would snoop for splitters etc. and try to bill you. Your main weapon was to threaten to go elsewhere, in which case they would back off.

AT&T should price their data plans and let the users decide how they chose to use them. End of story.

The ToS that says I will break my service contract if AT&T breaks the terms of their service.

Companies should be sued for false advertising for using the word, "unlimited".

It's not "unlimited". It's bullsh!t.
@Economister

Agreed.

@Real World

It's consistent with the ToS I agreed to, because I signed up at T-mobile rather than get screwed by AT&T's BS. It's a shame SBC bought them. AT&T wireless was the only mobile carrier I ever liked.
@Economister
Agreed.

in this age, i am trying to consolidate. if i want 1 gb of data, i have to pay $40 to put half on my phone and another $40 to add the other half to on my laptop.. come on.

It is THEIR network. Same as you renting a house as a residence vs a business. You usually charge more if it is used as a business!
This is bogus. Their data plan is UNLIMITED!!! This means that, i gould download 100TB of data a month on my phone and it still fits in the plan. If this is not the case the term unlimited does not apply and it's false advertising. Tethering is using a data plan on a phone to link other devices. THE SAME PLAN! The fact that phone companies can get away with double billing their customers is rediculous. three words-class action lawsuit. bury them in litigation. If I'm stuck paying $30/mo for a data plan that isn't even as fast as my home network, I better damn well get unlimited everything on it.

josephmartins Updated - 18th Mar 2011
@KBot

Out of curiosity is there no Fair Use clause in your Unlimited Plan's fine print? Or perhaps a clause that specifically addresses tethering? I ask only because there usually are such clauses buried deep in the fine print of ISPs/Telecoms. If so, they may be able to use it to enforce unauthorized use.

It stinks, I agree. And I think they're going about it the wrong way (auto opt-in) but they may be within their rights if it's in the terms of use.
@josephmartins

No, a lawyer doesn't get to double bill his time because he puts into the fine print of all of his contracts that he may, at his option, choose to double bill, when he decides that he could use more money. Fine print is not free license to screw people. As AT&T is a subsidiary of the phone monopoly SBC, I would argue that they are violating COMMON CARRIER. Maybe the FCC and DOJ will finally finish the job the started 35 years ago, but I doubt it.
@josephmartins

Little problem with those TOS's.... THEY DON'T STAND UP IN COURT! When someone takes the companies to court over these things, they usually settle immediately because they know that most judges would do a "Wait a minute.... VOID!" because these TOS's violate state or federal law.
@tkejlboom

You're an idiot. They're not double billing for the SAME USAGE so it's nowhere near close to being the same as a lawyer double billing for the same minutes.

Your data-usage is for your SMARTPHONE. You agreed to it. If you don't like it, go somewhere else (oh wait, ALL carriers are the same). They sell tethering and mobile hotspots for a reason.

You buying a car doesn't mean you get all the options for free. You can add them yourself later but you pay for them, unless you steal them of course. But then your analagous to this, stealing data.

@KBot
It's a WIRELESS SERVICE using limited bandwidth. It's attitudes like yours that bring about these crackdowns in the first place. You're probably the jerk on the plane trying to watch streaming video and sapping everyone else's GoGo bandwidth.

But thinking this through, your argument does bring up a good point: This policy should only apply to people on UNLIMITED data plans. People with data caps are already guaranteed not to abuse the system, so they in fact should be allowed to use any device they want. They aren't able to "abuse" the system anyway.
@dgurney So he's a jerk for using advertised services he's paid for? And you agree with carriers selling "unlimited" plans their network can't support, then reneging. You must be one of those company-is-always-right superconsumers, huh?
Sheesh!
@KBot
I'm sorry to have to take the side of a mobile network, who let's face it have ripped us all off for years by charging extortionate amounts of money for almost everything, from phone calls, to 160 character text messages and 100kb MMS, claiming that they are making huge infrastructure investments, although any idiot can tell that the nationwide coverage has changed not a jot in over a decade. Yes, I have no love for mobile carriers.... but -

I don't think this attitude is fair at all. 'Unlimited' in this context, under a fair use policy, OBVIOUSLY implies that unlike most networks you will not be BILLED for the amount of data you use. It is not a lot to ask that you use the data in the intended manner. By all means, watch YouTube videos on your phone, check your e-mail, download things if you must - ON YOUR PHONE.

What makes you think it is fair to hook it up to your laptop and fire up BitTorrent???

Of course, even though most people have perfectly adequate, unlimited and cheap internet access at home, many still feel the need to do the same thing they do with almost everything, which is take the rip out of it.....
@Traxxion What makes you think it's fair to allow users to stream Netflix for an entire day on their phone, but disallow me to connect my laptop for simple web browsing?

I have read of people getting these messages about tethering while using very reasonable amounts of data, sometimes below 2gb. I use tethering as a supplement when I'm not at home, not as my primary home internet connection for running BitTorrent all day.

If the amount of data I use in a month is within reason, why should AT&T care if it's from tethering or from local use? The largest amount of data I have used in a single month was 2.9gb, and that was at a time well before I ever used my phone to tether. I have only exceeded 2gb about 3 times.

If I was on the 2gb plan, I would have only had to pay an extra $10 for those 3 months. Why should I be forced into paying $45/mo every singe month just for the ability to tether?

Shouldn't I be allowed to stay on the 2gb plan and only pay additional when I exceed the data limit. The price for 4gb of data would be the same for either plan, but on a low use month ATT will essentially be taking my money and giving me nothing in return.

Illegal wiretapping
guihombre 18th Mar 2011
So that iOS update included a method for ATnT to monitor tethering?

Creepy, very creepy.
@guihombre: ... and there, its headers may contain original IP from which data request is done.

If the data is requested right from the iPhone, then the original IP is going to be what AT&T is assigned to the device when it connected to the wireless network.

However, if the device is working as relayer/tethering one, then origial IP would be different -- something like 192.168.*.* or 127.*.*.*.
@denisrs
The IP has to be routable. It can't be 127.x.x.x or 192.168.x.x when it hit's AT&T's network. 127.0.0.0/8 is always localhost, so that won't leave the NIC.
@denisrs Bzzzzzt. Wrong.
@denisrs
So a virtual machine on my phone would likely be viewed as a tether?
127. anything is local loop back you do not even need a NIC for that network IP to be used.
Another reason to avoid the iPhone. Like we really needed any more.
@Droid101
This has nothing to do with iPhone. since it is more used on AT&T networks, it has become one. If tomorrow any of the ad phones pickup on their network then it would be that.

When is 2 GB *not* 2 GB?
bmgoodman Updated - 18th Mar 2011
Basically, AT&T is saying to pay them $25 for 2 GB of data, but only for devices where it's not practical to actually use that much! Sure, pay them $25 each month for your abacus. If you have a device that might actually USE the 2 GB you pay for, then they want to charge more. If you go over your limit, they charge still more.

Look at the Motorola Atrix smart phone. You pay $25 for your 2 GB of data, but if you connect it to the dock ("like" a laptop, but really just a bigger screen and keyboard with a full browser) you suddenly pay for TETHERING? What, exactly are you TETHERING since the "dock" is just a screen and keyboard?

If you connect your smart phone to an HDTV via HDMI and also connect a wireless keyboard, are you TETHERING?

Sadly, the Wireless CARTEL is still firmly in control. Higher prices bringing higher profits buying more access to more politicians.

I don't have a jailbroken iPhone4 so I can't currently tether for free, but regardless I find it to just be greedy on AT&T's part.

I have an unlimited data plan for iPhone (hooray for being grandfathered in!), which pretty much means I will be with AT&T and iPhones for a long time, but if they think I am going to pay them extra money for limited tethering capabilities on top of my unlimited plan already, they are crazy. That just doesn't make any sense.
@Bates_
Actually your not grandfathered in. AT&T only has to keep you on that plan for the duration of the last contract you signed ie a 2 year contract keeps you good year 3 AT&T can tell you the agreement is up and you need a new contract and the unlimited is no longer avaliable which is what they have been seen doing. The fact is to be on AT&T and use an Iphone is just 2 huge mistakes.

Pete "athynz" Athens 18th Mar 2011
@Fletchguy That's not accurate. I had unlimited data when I first bought my iPhone 3G over two and a half years ago. About 4 months ago I went from that iPhone 3G to an iPhone 4 - AFTER AT&T did away with the unlimited data plans BTW - and my data plan was unchanged. Unless you have proof to the contrary I'm calling bull on this.

And your "2 huge mistakes" is simply your own opinion not backed up by fact.
@Fletchguy

If you follow the fine print argument, I'm pretty sure data is specifically protected on the consumer end. AT&T traditionally hasn't touched people's existing plans, generating the "grandfather" effect, just because it would piss people off. You have no legal or contract protections of your plan.

When Unlimited is not.....
rhonin 18th Mar 2011
@Bates_
Not just the iPhone.
Before I signed my last contract with ATT I did confirm that the "grandfather" is for "smartphone" and is not specific to the iPhone.
So my son's Captivate is "unlimited" and my i4 is "unlimited".

But some folks are correct. ATT at any time can update with no approval from you the definition of "unlimited".

sad
@Fletchguy
I have been told every time I call about the Unlimited Granfathered plan and at stores.
So long as "I" do not cancel the service I can keep my plan that is for my laptop via a USB 3g data device. Thats about 4 years now.

Unlimited?
jokila 18th Mar 2011
@Bates_ When did ATT stop offering unlimited plans (or how do i know what kind of account i have)?
@jokila They stopped offering unlimited plans when the iPhone 4 came out. If you bought an iPhone 4 and you were under an unlimited data plan with your old iPhone you were grandfathered in. If you are a new iPhone4 customer you will have to pick one of the tiered data plans.
@Bates_
No, what you have is throttled unlimited after you hit your monthly data cap.
To those who think they have grandfathered unlimited plan, please try to hit 6GB in a month and your service will be immediately cut off. When you call to complain, you will be told that your unlimited plan has expired a long time ago and you need to sign a new one with a 2GB limit.

AT&T is just allowing people to believe they have unlimited plan because most of these people are paying more for what they actually use. They seldom hit the 5GB limit but are paying a lot more. It's a trick. And many have learned it the hard way.
@pogopeggy
I have confronted ATT about this unlimited account and a cap on my Data Plan for my LAPTOP device and what I use it for can not be capped.

I support Pharmacies, Hospitals/Drs offices, and other medical fields wireless. This all through a VPN connectionv VIA P2P sessions. I also use the laptop during storm season to chase severe weather. So I MUST have a true unlimited account and what I pay monthly for all the phones and data I think it is covered in the monthly payment. The manager agreed with this and noted and took off any caps. This is a case by case situation being that 4G coverage is not as good as 3Gs established service and devices. WIFI hotspots are not an option for the DATA that I deal with and ATT does not want to get into HIPPA violations forcing me out of the plan that I have.
@pogopeggy You want to back this up with any proof? I used to tether my jail broken 3G and before that had a "unlimited" card for the laptop through AT&T. I always knew the "unlimited" plan was really a 5GB plan but in the few instances that I went to 6GB or more a month I still had no issues. You also talk about paying a lot more for an unlimited plan but it doesn't add up. The new 2GB plan is $25/mo yet I pay $30/mo for my "unlimited" 5GB plan. The additional $5/mo sure doesn't seem like "a lot more" for 150% more data.

Exemptions...
pogopeggy 18th Mar 2011
Maybe AT&T does exempt people in the emergency and medical field from the data cap. But that all it is: an exemption. Which means most of us are under data caps. Those who think they are grandfathered... try to push your usage beyond the 5GB limit. I bet you'll be fuming mad the next morning.
@pogopeggy As I mentioned above, I have with no exemptions and no issues. I can certainly understand how it would happen to somebody that used 2 or 3 times that every month though.

It is in the terms of service. You agreed to it. I would love cheaper data plans and the ability to tether for free. But, if I sign a contract then I have to abide by it.
