With all this stuff about radiation and considering how much I'm on the phone in the car, I decided to switch to earplugs. I got this 30 dollar rubber tipped pair from Verizon called "mega bass" or something. If you drop one earplug it acts as a headset and the call quality is great. I do have a bt earpiece, but they say that's not a guarantee of no radiation either. So, back to a wire. The bonus is that it plays music on the DROID X amazingly. AMAZING! I had no idea how good a music player the DX is. I feel like I've just rediscovered my phone.
