So I have a bit of a situation. I needed to restore my phone through settings/general/reset on the phone and well I clicked it my phone did it but when it started again it went into the apple logo screen. It has been stuck there since. It won't let me hard reset and I've tried disconnecting the battery and the phone turns off but when turned on again it's just that same screen. it was a jailbroken iPhone 4 and I was on iOS 4.0.1 when it happened. help?
