Hello, I have an iPhone 3GS 32 GB that kept freezing intermittent. It bug me for a while. It is jailbroken and unlock with t-mobile. So i decided to "erased content and settings" and ofcourse I did backed up my iphone. So now, after i click on this setting which has been running for 5 hours, the screen stays black with the apple logo. The capacity that was used on my iphone was not even more than 5GB. So, i'm in the black screen with apple logo for 5 hours...worried...if the iphone will ever come back on again. I tried to do the "DFU" mode by holding the power and home button for 5 secs, then let go of the power button keeping the home button press for 25 seconds..but all it does is put me back to the same apple logo.. Before i did the "DFU" mode, the phone would flicker once every 45 minutes then comes back to apple logo again. All help is greatly appreciated.
