I bought an iphone 2g off ebay, was unlocked and jailbroken with pwnage tool, has 3.1.2. I have a t-mobile sim, when I put it in I have no service. It recognizes my sim and phone number and all, just has "no service".
What do I need to do? Do I need to re-unlock/jailbreak it, and Can I even do that? Is there a simple solution?
Im very new at this, so Im pretty clueless. Please help me!

Did you confirm that it was in working condition before you purchased it? There are some 2G phones that have had their seczone, baseband or baseband bootloader corrupted by attempts to unlock with incorrect tools.

The best way to confirm this is to restore via DFU mode to OS 3.1.2 and then jailbreak using redsn0w

Do not use OS 3.1.3

Done and Done and my iPhone now works PERFECT. Thanks so much! I have been at this for over a week now, asked a lot of people a lot of questions and tried a lot of things, and to no avail.
So thanks for the help!
