I'm trying to get sprint to either give me another phone or refund my money (combination of their rebuy program plus the difference to what I paid for the phone) b/c it's their fault they said the phone was fine, so I don't want to root or flash and screw something up. So I'm going wait to see what they come back with first.
No, I did not mentioned that it still shows the previous owners phone #, but I found it odd. I don't know if that's normal for sprint android phones, I've been with sprint only around 5 months and had been using iPhones. I'm going to bring that up when I talk to them again next week.
