Hey everyone just tellin u: do not install rotation toggle off of cydia. I had a jailbroken 3.0 3gs and when I installed it it crashed the springboard and put it in safe mode, then started restarting the whole phone as well (apple logo) repetitiively. So basically it would rotate between my lock screen, the apple logo, the safe mode notification screen every couple seconds. Went on for about 10 minutes before I connected to iTunes in recovery mode an had to do a full restore. Just tellin everyone so u don't make my mistake
