I have an iPod Touch 3G jailbroken with Greenpois0n's RC5 Beta4 software on iOS 4.2.1, and was wondering why every time I install LSRotator in Cydia, whether from the official repository or from a cracked one, it causes the springboard to crash. I was previously jailbroken on Redsn0w's 0.96b4 software and it worked fine then on iOS 4.2.1. Is there a way to fix this?
