iOS 7 installed? Check.

Life is good and time to fire up your favorite, right?
Not so fast.
Before diving into the beautiful, parallaxy, candy-colored world that is iOS 7, you need to adjust your privacy settings on your iPhone or iPad. If you like your Privacy, that is. Installing iOS 7 is pretty easy and, even if you don't, it will usually put everything back right where it belongs.
Well yes, that's how iOS 7 is designed to work. But don't let Apple's thin Helvetica Neue and and serene, dynamic wallpapers lull you into complacency. A whole number iOS upgrade is a big deal and it resets a bunch of your settings and adds privacy and security settings that you should be aware of.
Apple hides its System Services settings all the way down at the bottom of the Privacy > Location Services panel. If you've owned your iPhone for more than a few months you'll have dozens (possibly over one hundred) apps listed on this screen, making it a very long scroll. If you actually make it to the bottom of the list (most people don't) you'll see the fabled System Services setting and the explanation of what that little purple arrow icons means.
Again, the path is Settings > Privacy > Location Services > System Services:
Learn this screen and commit the meanings of the three little arrow icons to memory. Then notice when they appear in the top right of your iOS menu bar and come back to Settings > Privacy > Location Services to see which apps are using your location data. Audit this screen frequently to disable location access for apps that don't need it.
Then touch System Services to reveal the most important privacy settings on your iPhone or iPad.
- Settings > Privacy > Location Services > System Services
I recommend turning OFF the following:
- Settings > Privacy > Location Services > System Services > Diagnostics & Usage
- Settings > Privacy > Location Services > System Services > Location-Based iAds
- Settings > Privacy > Location Services > System Services > Frequent Locations
Diagnostics & Usage
This setting monitors everything you do on your iPhone and "anonymously" sends it to Apple for "improving iOS." Whatever. It's just like when all the major software companies changed their install screens from "send usage data?" to "customer experience program" or some such nonsense. If you leave the "Diagnostics & Usage" option on, you're giving Apple permission to monitor and record everything you do on your device.
Frequent Locations is equally bad, if not more so. There was a big stir about this when iOS 7 beta 5 was released, and the data it captures about your whereabouts can be downright creepy. For many it brought back memories of the Locationgate fiasco from iOS 4 in April 2011 when a database of Wi-Fi hotspots and cell towers around your current location known as "Consolidated.db" was discovered on iOS 4 devices -- and the computers they're backed up to. Note that the iPhone 4 (and earlier) do not support the "Frequent Locations" feature in iOS 7.
Next navigate to the iOS Advertising Privacy settings (Settings > Privacy > Advertising).
Here, you should do three things:
- Turn ON "Limit Ad Tracking"
- Touch "Reset Advertising Identifier" (which I in January 2013), and
- Touch "Learn More" and learn about what an "Advertising Identifier" is
Navigate to the iOS Safari Settings (Settings > Safari) turn on the following:
- Block Pop-ups
- Do Not Track*
- Block Cookies is set to "From third parties and advertisers"
- Fraudulent Website Warning
*Apple's one of the few companies that still supports the aging Do Not Track standard in its mobile Web browser. Even if it is considered dead (my ZDNet colleague Ed Bott called it " ,") I turn it on anyway, for the few web servers that actually respect it.
While you're at it it doesn't hurt to touch "Clear History" and "Clear Cookies and Data" now and again.
Update 2013-1121: Added more Safari settings and a note that the iPhone 4 (and earlier) do not support the "Frequent Locations" feature in iOS 7.
