The only current way includes you upgrading to iPad baseband which is unlockable with Ultrasn0w 1.2.

Use redsn0w 0.9.6rc8 to do this, however note that this will result in loosing GPS functionality and can NOT be downgraded until a new hack is found.

If you don't need the unlock, don't do this, otherwise it might be a good trade to have a functional phone, i have actually done this trade-off.
