A while back, my iPhone 3G went through water damage and... was destroyed. I'm not eligable for a upgrade until may, but my mom is. Will they let her go in, buy the iPhone (3G refurb for $49) and put on it on account (which already has the iphone data plan) or will she have to pay $30/month from now on? Or could my dad give me his iPhone 3G (hes on a whole separate AT&T account), get a new one, i pop my sim in his and be fine. Or will it go through activation issues and will i have to ultrasn0w it, in which case is it even worth it? what should i do?
