First of all is it possible on a Windows or at all on 3.1.2.

If so here is what I have done so far. I updated to 3.1.2 via Windows and Newest iTunes. I activated with my AT&T simcard and jailbroke with blackra1n. IDK if that was the correct jailbreak to do. I then downloaded ultrasn0w via the repo666.ultrasn0w.com repo.

If I am doing something wrong can someone please help me because I am doing this for a friend who lives in Canada and uses Rogers Cell Service and he leaves Friday.

I will continue to search online but if you could help that would be awesome and THX will be given.

THANK YOU

***On my About Section under Modem Firmware it says 04.05.04_G. IDK if that was the Baseband or not just though I would add it.
