So I'm new to this whole thing, I went through redsn0w and it seems to be fine except how do I get my 3Gs back on rogers, as right now I don't have a cell number or service according to my iPhone lol. Thanks.
Was it unlocked when you bought it? Did you buy the phone new from Rogers or elsewhere in Canada? If so, you shouldn't need to unlock it. Try rebooting. If you bought it on eBay, you'll probably need to unlock it with ultrasn0w as it may be locked to AT&T.
