Wierdest thing just happened:
Took my phone with me on a camping trip and was wading through knee deep water and must've absorbed some moisture into the phone. The touch screen became finicky afterwards; working only intermittently and mostly just on one half of the screen with the right edge being completely unresponsive. The left side required very hard pushing to work. Tried to let the phone air out, compressed air dust buster, hard reset, soft reset, ROM reflash, etc. No luck; was about to take the phone to a repair store the following day, but decided to activate a backup phone in the meantime so I could get calls. (Mogul was stuck on screen config screen so it was non-functional).
Right before I took the Mogul to the repair center, I reactivated it. Ta-da, the screen now *works* (crosses fingers and no jinxing...). ??? Any idea why or how this happened? I'm not complaining, but I'm severely confused, in a good way.
