PPCGeeks - Messed up voice calls (static+high pitch)

First of all, if any of you shake the phone gently, do you hear anything? I do.. not sure if it's normal.

Anyway, i'm getting a bit of static like interference on my voice calls through the ear piece. For example, when its ringing, every other ring will go up in pitch all static like. It's not a constant pitch change. And then when people are talking, it'll make it hard to hear sometimes cuz the pitch is too high.

I'm running the Juicy R3 rom, and have not flashed the radio. On Sprint. Everything is fine through speaker, so i'm not sure if it's a radio problem as opposed to a hardware problem.

All else fails I guess i can use TEP to get another one, but would like to know if anyone else has experienced it and fixed it. I've had this phone for under a week, and it didn't start out like this.
