Issues with volume cutting in and out on calls

[TRD_Power]

First off, I cannot wait to rid myself of this god awful device. By far the worst phone I've ever had and easily the most unreliable. On top of many other problems, all the sudden my 8320 started cutting in and out on calls. When I look at the phone, the little volume control bar to the right of the screen flickers from full to none constantly. The phone will just do this out of the middle of nowhere, mostly during a call, but sometimes right from the get go when trying to place a call. Samsung needs to hurry and release the Galaxy S2 so I can be free! Any info on how to fix this (besides a .308 through the screen) would be greatly appreciated! Have to use this thing for another month or so
