I have an IPhone 2G that I have been using on TMobile for six months. Just yesterday while traveling in Washington DC my phone was unable to pick up a signal.

This has continued all day today. I went to a TMobile store to check out the sim card and it immediately picked up a signal in another phone.

I have tried to restore to the factory settings and rerun QuickPwn on the phone. Same behavior.

I am getting ready to try Pwnage on the phone, but I am wondering if anyone else knows of a problem here. The phone has been working fine otherwise, wifi is OK, etc.
