Good luck!

The following is for a Windows PC - for a Mac check out the link above. I used my Windows machine over my Mac for simplicity.

1 - Open iTunes
2 - Get your iPhone in DFU mode
3 - Select restore iphone (using the original 2.2.1 firmware, not a custom one)
4 - Let your iPhone do the restart process until you get ERROR 1013
5 - Close iTunes
6 - Open Quickpwn. you will get a message saying to hold power and home for 15 seconds.
7 - Turn on your iPhone by holding power button for 2 seconds
8 - Open iTunes and your iPhone is recognized and activated
