Hi everyone, I'm looking to upgrade my sprint pre, as it has started acting crappy, speaker blew out, middle button unresponsive. I'm surprised its lasted as long as it has. What i'm wondering is where the best place to upgrade is, i've never done it with sprint. Do i have to trade in my phone to get the new one? Or is there a buy back deal? Also if anyone knows of any upcoming deals for the Epic 4g or if theres a device thats supposed to blow it out of the water soon it would be appreciated. thx
