Wiping old iPhone without touch or me.com? I want to sell an old iPhone 3G for a few bucs... But I have a problem: the touch screen of the phone is broken and the phone has no internet-connectivity. 

Is there any chance to delete the content on the phone? I can still make backups with iTunes.

Thanks for help :-)
If you can connect it to a PC/Mac, you can fully restore the phone using iTunes.
