Hi! This is my first post re my first iPhone. It`s a 3G and I bought it jailbreaked and unlocked using 3.1.0.2 firmware. For reasons too numerous to tell I mistakenly tried to remove my details from the phone using "Erase all content and Settings". The result is iTunes says the SIM is not supported. When trying to restore the phone it will go so far and then shows a "1015" error. The phone screen is stuck showing the USB and iTunes logos. I`m hoping my foolishness hasn`t trashed the phone. Any advice would be greatfuly received.

Thanks
