Phone freezing during calls

[dysfunkshun]

Lately, my phone has been freezing a lot, mainly during calls.  At the end of a call, the screen will freeze and continue the call, not letting me hang up or press any other buttons, causing me to have to pull the battery.  Its also happened a couple times after getting a text.  All I can do is pull the battery to unfreeze it, and its getting rather annoying to do 2-3 times a day.  Anyone else having this problem and know how to fix it?

Dahhh!!  Yah.  not only does my phone freeze when I try to hang-up, but it also freezes when I get incoming calls, which I miss and have to call back.
