I DO NOT TAKE CREDIT FOR THIS! 1. Attempt a restore of 2.2.1 in DFU Mode 2. Get the iTunes error message. 3. Reset device 4. Launch QuickPwn 5. Press next and get past the first 3 steps. 6. Bam, phone is fixed. EDIT: It does work, just tried. iPhones baseband will still be updated but 2.2.1 works fine on it.
