Step 1: Upgrade iTunes
To upgrade your iPhone or iPod Touch to Apple's iOS 4 firmware, make sure you're running the latest version of iTunes on your computer. Here's a link to iTunes 9.2 from CNET's Download.com. After installation, you may need to restart your computer.

I keep clicking "Check 4 update" but nothing yet. 3.1.3 is latest for my iPhone 3GS.
Same here. Anybody know at what time today? Or was this just another come-on.
OK. So I did a backup, which took only a short while. Then when I start the update, it does another backup that lasts forever. I can't find a way to skip the backup done before the install. Crap!
How much of your phone is "used memory"?
(I have 2gb used, out of 16gb.)
How long is "a short while" and "takes forever"?
10 minutes?
3 hours?

If have an iPhone 3G 8GB - upgrade to iOS4 went just fine. A bit disappointed - can't see or tell any difference. Hopefully there are some improvements for my older phone.
You don't see *ANY* of the 100 new features at all?
No folders?
No backgrounds?
No 1-box email?
No changes of any kind?
Then you aren't running 4.

Hi- I have I pod touch (second generation), and I updated to I OS 4- but, I don't see any folders either. Maybe the second generation doesn't get that feature? Or, how do I access the folders?

Same here. I upgraded my iPhone 3G, there were no problems, glitches or error messages. I can see no difference whatsoever to my phone. Very disappointing

Why is the back up taking so long??? I have the 3g and the backup has been backing up for almost an hour??
@Pmusick
I had the same problem - any solution? I left mine for over an hour, then had to go to bed, so killed it.
Does it eventually finish?

I have a 3GS. Got iOS 4 yesterday. Downloaded fine. Started to backup and I aborted the process after 2 hours. Right now it's been backing up for an hour and it only appears to be 1/4 way thru the process. VERY slow. It's a 16GB drive and it's maybe 20% full of pix, apps, etc. AND before I started this backup (upgrade) today, I deleted 10-12 apps I hadn't used in a while to try to speed it up. So far I'm not seeing an improvement. Ugh.
I let it run for almost 8 hours two different times today (16 hours total) and it go beyond about 1/8th of the backup stage less actually install iOS4. Pretty disappointed. Anyone know how to skip the backup and go right to the install? Is it even worth the upgrade on an iPhone 3G?
Just completed the 4.0 upgrade to my 3G and see no difference.
Actually I did for a brief instance. It then did the usual bit about upgrading and verifying firmware and then said 'iPhone restored to factory settings' or something similar and was followed by 'Restoring from backup', told me it had restored from 'today's' backup and restarted, restored apps, restored music and videos. Then a carrier update.
After what was probably almost 2 hrs it was done and it seems to be the same old o/s, no new features, nothing...
Has anyone else experienced this?
