First we showed you how to add the multitouch gestures to an iPhone 4 running iOS 4.3 beta, and today we’re going to show you how to make your iPhone more like the iPad by adding hardware rotation lock.
1. Jailbreak iOS 4.3 beta
3. SSH into your iPhone and browse to /Applications/Preferences.app/ and backupgeneral.plist and settings.plist. Now over-write them with the ones you just downloaded
4. Go to /var/mobile/library/preferences/ and edit com.apple.springboard.plist.Add SBUseSystemGestures as a key and set it as true.
5. Go to System/Library/CoreServices/SpringBoard.app/ and edit N90.plist.Add multitasking-gestures as a compatibility and set it to true.
6. Reboot and enjoy. Now you can use your mute ON/OFF switcher on your iPhone as a rotation lock.
