keyboard buttons typing wrong letters?

My 8310 has on several occasions now completely gone off tilt and typed the letters "yi" in place of my "T, Y, I, and D" keys. I have to push my keypad buttons a thousand times before it finally begins typing the correct letter for that button. Anyone seen this? I'm losing my faith in this phone quickly with the now loose usb charging connection, the constant battery pulls, the dust behind the screen, my keyboard lock wont unlock at times, and now the "yi" syndrome!! :mad:

Mine does about everything you're talking about (constant battery pulls, random keyboard buttons, loose usb port) hence reason why soon I will be getting a new phone because I really don't like my Curve anymore. It's also super slow.

It sounds like moisture damage. You can either file an insurance claim or replace the parts that are broken if you do not have insurance.
