How do I unlock my iphone 3g?

[elggy]

Anyone know how to jailbreak or unlock the 3g from 4.1 yet? I did something stupid and I downloaded the new 4.1 and it locked my phone, anyone have any suggestions of what I can do or should do? My phone won't work at all, I'm trying to get it to work for tmobile but it wont even work if I put an at&t SIM in

nothing at all? Do I just have to wait for someone to come out with a new jailbreaking system?
