Well, I went to the nokia repair site and punched in my serial number and apparently I am under warranty for 10 more days and I don't need to provide the original receipt (good, because I don't have it!). I guess I'll send it in and see what happens.
Actually for me it's more around the center of the screen. So, it's actually still barely usable, I just use the hardware buttons for dialogs that appear in the center of the screen. Of course, the fullscreen keyboard is completely unusable at this point.
