FMTalk, i910, and FAST Battery Drain, Hoping somebody can help

I'm hoping somebody has had a similar experience and can help me.

I recently bought a FMTalk FM Transmitter that plugs directly into the Omnia's multi port, and comes with a car lighter adapter that plugs into the FMTalk module via miniUSB (to only power the unit, not charge the phone).

The problem exists whether the FMTalk unit is plugged into the car lighter adapter or not... just being plugged into the phone is enough to reproduce this behavior. Upon plugging the unit into the Omnia, the batter will drain 5% every 4 seconds or so, until it's reporting dead. During this happening, the phone (not the battery, but the lower portion of the phone where the internal electronics are) will get very hot.

I'm hoping that somebody can help me resolve this issue.

Thanks!
