Anyone else's touch screen stop working?

So, I've googled and apparently this a common thing for the xenon and i'm pretty pissed off by it. My phone has been acting odd for about 2 weeks. It started out just randomly pushing the wrong button from what I actually pushed. Like I would push the message button and it would bring up the menu or if I clicked to read a message, it would hit ignore. It was annoying, but it came and went so it wasn't too awful. But two days ago, the touch screen just stopped working all together. It brings up the main screen and I can use the send and end buttons as well as the QWERTY keyboard to make phone calls so it's strickly the screen part. Also, the date and time have mysteriously changed themselves to January 1st, 2009. Which is weird, since I didn't even get the phone til June 09'. I'm just pretty irritated and i'm hoping maybe someone else has found a solution to this problem that doesn't involve me wasting a lot of money for nothing. I'm thinking maybe it's the battery? but it still charges and the battery holds a charge so I have no idea what it is. I have no warranty on it, since it's been over a year and i'm not due for an upgrade yet. Blehhh. Help!

Just the date and time that i'm aware of. It hasn't gotten wet though I must confess, I drop my phones all the time. I've never dropped it from a very far distance though and I didn't know dropping a phone could cause the touchscreen to go out. Thats weird, because there is no damage to the phone, barely any scratches. I'm due for an upgrade soon though, i'm just going to get an iphone and protective cover this time around.

We got 3 Xenons last December.  The touch screen on one stopped responding in July, while on vacation.  Never dropped or got wet.  Another phone had similar problems this week.  The upper half of the touch screen stopped responding.  Instead, the closest button on the lower half would respond.  Today nothing worked.  ATT is sending a replacement.  The first replacement is still working.  Oddly, of the 3 original phones, the longest lasting is the one most abused.  I love the full keyboard, but there are serious problems with the touch screen.  I only hope we can make it through the next 14 months with these clunkers.  Full keyboard: YES.  Touch screen: NEVER AGAIN!
