BB Bold :: It Gets Very Hot While Talking

I used to have the BB Tour but, due to an unfortunate incident involving some water, it had to be replaced. While the phone had a few quirks, overall I was pleased with my BB so I decided to get another one. I'm starting to think that was a mistake. This phone gets very hot during calls. I'm assuming it has something to do with the heat that also causes the battery to drain quite quickly. There is also an extremely annoying quirk of the audio cutting in and out during calls. This only lasts for a second or two but happens repeatedly throughout any given call
