Okay, im some what new to this. My brother had got an iphone. so i got one. we both have tmobile. But i got mine already unlocked, jailbroke, and activated. just yesterday I plugged my iphone up to a mac. So i come back get my phone. and its in recovery mode. i was pissed. I get in the car and he said he did it. but to make a long stry short. I used pwnage i created the costom ipsw. i restored it with the update on itunes 8. That did work but now it wont recognize the sim because its tmobile. I dont know what to do. So i put it in dfu mode again and i try and install my costom ipsw. An error pops up as error 1600, and 21. Im stuck. help please

Did you try putting it in DFU mode? Hold power and home until it turns off. Then let go of the power button and keep holding the home button till iTunes recognizes it, and then try restoring it one more time and it should work.

or, why not just restore to original firmware on mac, then use quickpwn for mac and your set...easier then ever
