Hey, does anyone have an old iPhone 4 or 4S they don't need and want to sell, preferably AT&T? My wife has managed to wreck her phone yet again and we don't have an upgrade so it's like $350 to buy a new one even with renewing the contract. Yet this is a phone they give away to new subscribers. And we don't want to just ditch AT&T because we have their eternal unlimited data thing since we subscribed to it before they started charging for limited plans.
