Motorola V500 / V525 / V505

Are there any compatibility issues with this phone and Cingular's network? I saw on Amazon that this phone is still listed (for -$150!!) as an AT&T phone and I'm wondering why its not listed as a Cingular phone. Any comments on its performance on the new Cingular would be appreciated.

Also, I can't find anywhere what Bluetooth functions this phone supports. I assume it supports Handsfree Profile. Does it support Object Push Profile? I'm trying to figure out whether it is compatible with my car....

Thanks in advance for any help.
