Can anyone point me to a place/site to buy a replacement phone? I need to replace my daughters iPhone 4. We have Verizon, and due to my plan, I can't do any upgrades without losing my plan (grandfathered unlimited plan). I need to get her one now, and then Droids will be next for the rest of us. I tried Swappa.com but it is so hard to find a decent seller on there. These phones are expensive, I don't want problems, ya know. Anyone know any good info on stores/sites I can check out?
