This is the 2nd time now that this has happened, and both times it has been when my phone was plugged into an outlet and charging. I was on a bus ride and had my phone charging while I was using it pretty heavily - Google Talk, web viewing, etc. Basically, some aspects of the screen would stop working. For instance, the "space bar" wouldn't register when I touched it, and certain other letters. Overall, the touch screen was pretty unresponsive. The problem only went away later after I had unplugged it for some time. During this problem, I reset the phone, reset the calibration - nothing worked. Is this a bug? Anyone else have this problem? Thanks. Oh also, I noticed my phone was pretty hot.
