Using Yellowsn0w with original provider
I have a Rogers locked phone using it with a rogers sim card. I also have an ATT sim card because i travel to the US a lot and use it there. So my question is, do i update my phone to 2.2 or restore it? whats the different (sorry i'm sure its a stupid question but i dunno). Also since i'm using it with rogers am i supposed to restore it, then activate it before i quickpwn it? or should i update it to 2.2 unplug it and then use quickpwn right away (without activation)?
Thanks for all your help :D
