Hello, I am wanting to sell my iPhone but before I do so, I would like to wipe it clean of all my information. I tried restoring it in iTunes but I kept getting an error 3004 or else it said it could not connect to the server (or something along the lines of that). So I figured if that will not work, I will "erase all content and settings" I have attempted this twice now: the first time was for 3hrs, the second time was for 12hrs. When I press the button I just get a loading wheel sign, no logo, no loading bar. After it taking so long I rebooted my phone and all the same content was still there. How do I fix this?! iphone details: 3GS 8GB version 4.3.5 modem firmware 05.16.02 jailbroken with redsn0w for mac Your help would be greatly appreciated, Thank you!
