Immediately after I updated the firmware and has džejlbrejk on his own Guide same, I questioned the system multi-touch-gestures in iPhone. Unfortunately, it turned out that the method used in GM, 4 3 doesn’t work in 4.3.1 (if any?), so we had to find another.
I gathered all the information in a bunch and now you can in just a couple of minutes the system gestures on your iPhone 4.
Step 1: for the download file containing the files.
Step 2: to get computer access to the file system by using a file browser for the iPhone.
Step 3: , replace the following files from the downloaded archive:
/System/Library/CoreServices/SpringBoard.app/N90AP.plist
/var/mobile/Library/Preferences/com.apple.springboard.plist
/Applications/Preferences.app/General.plist
/Applications/Preferences.app/Settings.plist
Step 3: restart your device, go to settings and turn on the new switch.
Congratulations, everything, now your iPhone 4 is multi-touch-sign function!
