This week's tips will show you how to prevent a thief from turning off Find My iPhone and we'll look at how to force quit apps on iOS 4.0 and above. We'll also take a look at how to increase your tapping potential within certain apps, and you'll be surprised about what you can do when tapping with one or two fingers. You'll definitely have some more useful tips to use and show off to your friends.
Lockdown Find My iPhone
It can be very easy to turn off Find My iPhone if you don't have a passcode on your iPhone, iPad, or iPod touch. If you want to keep someone from turning it off the perform the following steps: launch the Settings App, tap General > Restrictions > Turn on Restrictions. You'll be prompted for a four digit passcode and then again to verify it. This passcode can be, and should be, different than the one you use to lock the screen. Finally, under the section titled Allow Changes turn the switches off for Location and Accounts.

No one will be able to turn off location services or Find My iPhone without the passcode. This is great if your iPhone is stolen, but not so when you are using your phone or apps that require location services. In the event that an app requiring location services isn't working you'll need to go back to the Allow Changes section and turn it on. Relaunch the app, after forcing it to quit, and try again. Once you get it working toggle the Location switch back to the off position.
Compatibility: iPhone, iPad, and iPod touch.
Force Quitting an App
Double tap the Home button to bring up the iOS Task Manager and then locate the app you want to force to quit. Tap and hold the icon for that app until it begins to wiggle. A red circle will appear with a white minus sign in the center superimposed over the icon. Tap the red circle and iOS will force the app to quit.

Compatibility: iPhone, iPad, and iPod touch running iOS 4.0 or higher.
Get More Out of Tapping in Google Maps
If you are using Google Maps, a double tap with one finger zooms in a level, a single tap with two fingers zooms out a level and a double tap with three fingers zooms out a lot further. Launch the Maps app and try this for yourself. If you experiment with it you'll get use to it fairly quickly.

Compatibility: iPhone, iPad, and iPod touch.
Even More Tapping Tips
If you double tap with one finger in Mobile Safari, or while viewing a photo in the Photos app, these apps will zoom in with the first double tap and then zoom out again with the next double tap.
If you are watching videos and you double tap the screen with one finger, you can then view the video in letterbox mode or non-letterbox mode.
Also, don't forget that double tapping while typing at the end of a sentence will insert a period and a space.

One finger double tap and you can get closer look at your pup's nose and sweet brown eyes in the Photo app.
Compatibility: iPhone, iPad, and iPod touch.
