Ok. I jailbroke my iphone last thursday (5th May) and everything was going good. I was able to download everything without a problem. And then today I was installing something from cydia and my phone just stallled on the apple logo. And is currently tuning on and off on its own constantly. I cant put the phone in dfu mode because my sleep/wake button is broke. I tried to connect it to the itunes but it wont recognise my device. Anybody, please HELP ME as soon as possible. Any ideas are welcome
