Delete a Game on Android
Android-based smartphones have the capability to access the Android Market, where you can download and install a large number of applications, including many games.
These games take up a bit of your device's memory when you install them, so when you decide to stop playing the game, you should always delete it from your device to free up space for more applications.
The Android Applications menu gives you all the tools you need to remove games from your device.

Tap the "Menu" button on your Android smartphone.
Tap "Settings" when it appears on the pop-up menu.
Flick your finger up the LCD screen to scroll down the Settings list.
Tap "Applications" when you locate it in the list, then tap "Manage Applications," which is just called Manage on some versions of the operating system.
Allow your device a few seconds to load all of your applications.

Flick your finger up the screen to scroll down the list of installed applications.
Tap the game that you want to delete.
Then tap the "Uninstall" button at the top of the game's information screen.
Tap "OK" to confirm your decision, and the device deletes the game.

touch is part of standard troubleshooting
procedure. Restoring your device will erase all
data from your iPhone or iPod touch, including
songs, videos, contacts, photos, calendar
information, and any other data. All iPhone or
iPod touch settings are restored to their factory
condition.
Whenever you restore your iPhone or iPod touch,
Apple highly recommends that you perform a sync
prior to restoring in order to back up any changes
since your last sync. If you have movie rentals on
the device, see this document before restoring.
Use the following steps to restore your iPhone or
iPod touch:
Make sure you have the latest version of iTunes
installed and running before attempting to update. Connect your iPhone or iPod touch to your
computer. Select your iPhone or iPod touch when it appears
in iTunes under Devices. Select the Summary tab. Select the Restore option. When prompted to back up your iPhone or iPod
touch's settings before restoring, select the Back
Up option (as seen in the image below). If have
just backed up the device, it is not necessary to
create another.
Select the Restore option when iTunes prompts you
(As long as you've backed up your device, you
should not have to worry about restoring your
phone).
Once the restore process has completed the iPhone
or iPod touch restarts and displays the Apple logo

Hello, Have you tried resetting the iPhone? Hold the main round button on the front in while also holding the small button on top of the unit in. Hold these both in until you see the screen change or it shuts down completely.

Solution i tried on Unlocked 1.1.3 and 1.1.4 versions. Just follow the steps they have been explained really easy way. Dont think this is too hard. Just follow them it will work:

1) download WinSCP on your PC (google it) and run the application
2) download new general.plist file on laptop
3) download OpenSSH on your iphone (its not show on iphone but its there so dont worry)
4) connect the laptop and iphone through the same wireless network and both will have separate ipaddress.
5) write the ipaddress from the iphone (Settings>Wifi>network details to which you are connected to shows you the ipaddress)
6) Goto laptop on WinSCP type the ipaddress of the iphone in host name field and username:root and password: alpine and then hit Login.
7) it will open like an explorer view of your iphone files on laptop then click on root left side. Click Applications> preferences> replace the general.plist file with the one you downloaded. Done the major part.
8) unplug iphone click Settings> General>Touch and reduce the senstivity to 0. 0 gives you the highest touch sensitivity.
9) Now be happy it works....
