I've read other threads on this topic but can't find an answer. My just purchased 2001 E320 has a snazy integrated cell phone, a TDMA Motorola which was a Verizon phone. I use AT&T/Cingular with a GSM phone. The question is whether it is possible to purchase a GSM phone that will plug into the cradle and be usable as an integrated phone. One would THINK so but I bet not. This is frustrating but hey, I didn't pay any extra for the phone.

Thanks all, for any experience you've had with this.
