Bought an original iPhone off eBay almost a year ago. Just sitting in my tech drawer rotting in its case. I tried downgrading it to 1.1.1 (even with the carrier update) from 3.1.3, no luck. For whatever reason, the AT&T SIM card still has the phone number attached to it, so I can activate it iTunes, but I can't make or receive phone calls.

Yours LCGuy is in amazing condition for the age though!
