After I updated to iOS 5.1, my iPad2 won't rotate anymore.
I updated to iOS 5.1. the other day, and my iPad2 won't rotate anymore even if the screen is not locked. I went to service center, and after testing the iPad's accelerometer playing some game, the guy at the service center thought that it is not a hardware problem, but more on the 5.1 update. Weird thing is, I enabled the "assistive touch" feature's "rotate screen" function, and the screen rotates, although with prompting. That is, it will rotate only after I choose or unchoose to either "rotate screen" to portrait or left or right. Anyone else who has experienced this? Any suggestions how to fix this?
