Hi fellow forumers, i decided to shut down my iphone after around 1-2 weeks of usage and now it is still at rebooting mode (the black screen with the apple). The thing is, it has been in this mode for approximately 4 hours already since i shut it down. Any help?

Erm guys, i have another problem. Any applications that i have installed got problems whereby when i opened the app, it will go back to the home screen. Any apps except default apps. It is like the home button got jammed or something but it is still responsive when i press the home button after using the default apps. Any idea?
