My phone has been busted going on two weeks now. It was liberating at first - I rarely answered it anyway - but now I'm starting to feel seriously disconnected. I almost took it in yesterday, but it started to work after 30" of baking in the hot sun on my dashboard. I wasn't about to spend fifty bucks if that's all it took to fix it, so never went to the Sprint store.
This morning it was back to acting up, so now I have it baking outside on the cement. I'm not sure why this should fix it, but I'm giving it a shot. That, and my last paycheck all went to bills & there's nothing left for the phone.
