I tried to unlock and jailbreak my iphone 3GS with the pwnage tool, but it doesn't work, always said the problem (connect the iphone to the itunes), so i saw another ways to unlock it, i try with the red snow and green poison (always on mac) and now my iphone its always with the black screen, it doesn't turn on, and when i plugged to the computer always said that it's on recovery mode, but when i try to update it (with a firmware created with pwnage tool or direct from the itunes) said that the device can't be recognized, so i can't do anything, i am very desperated. I don't know if there's any solution, or if it's a problem with the baseband, i have no idea. Pleas help!
