My iphone suddenly touch screen is not working.. cant slide to answer if a call comes.. no sensation at all...what to do ?
Is this a known problem with the iPhone or with unlocked iPhones? I rebooted it by holding the Home key and the shut down key on the top. it still now working..

So my final option is to restore my iphone via itunes.. any specific "procedule" need to take care??
And how to jailbreak?

Thanks
