Dang. Well, thanks for your help everybody. I took it into the sprint store today as they said it could be fixed and that my unit was actually still under warranty. Turns out I'll never know for sure because when I got there they said it needs to remain activated on my account for 30 days before they'll do any warranty-related work. I can only return it to the seller within 7 days, and the thing is, the display wasn't the only problem. The "end" key also wasn't functioning at all. I contacted the seller and he apologized and promised to swap it for a phone I'll "definitely like." I can see he's got a TP2 selling for $50 more than I paid for mine, so I can only assume it's in better shape. I'm giving him one more shot. We'll see what happens with the next one.

the sprint store said it would've been an easy fix, btw. For the display problem, all it needed was to replace a certain part. For the end key, though, if it turned out to be due to moisture or corrosion or something, it would become an insurance issue, and then there'd be the $100 deductible. At that point it's definitely not worth it. So -- back it goes to wherever the heck it came from.
