usb plug in broken

[wwefandavid]

Someone on craigslist is willing to trade their mogul for my nintendo ds with 3 games for it (with carying pouch) with some ps2 games, 1 xbox game, and $100 for their mogul. But i dont know if i should do it or not because their usb plug in is broken and they said they still have warrenty under it so i can fix it but thats only if i sign up with a sprint account. but i planing on signing up on cricket. so is their anyway i can fix it? because if not i dont want to trade because it would be worthless.
