Loss of touchscreen sensitivity would indicate hardware damage, especially if its only limited to a certain part of the screen.
Try rebooting your phone, if that doesn't work try restoring. I don't know what's causing the problem, but if its in anyway related to a software malfunction (that being the only thing we can really help you with here), this should solve it.
i have restored to 1.1.3 then to 1.1.4 then to 2.0.0 and still nothing it did work in the begging but when i upgraded from 1.1.3 to 2.0.0 by accident before they had the unlock for it so then i restored to 1.1.4 and thats when it stopped working
i just figured out that that part of the screen doesnt work at all in ipod mode i cant change volume
