I bought V600 last year in June, as soon as it came out thru Cingular Wireless.Phone kept losing connection with service. Every 10 minutes or so, if I am talking to someone, it would drop the connection. Even though I have full 4 bars on my connections.I returned it. Cingular does have great service, it sent me another phone, same model.This phone kept freezing up. So I sent that one back after a week.Cingular sends me another V600. This one has problem with the bluetooth module, and did a automatic reboot of itself.Finally, I gave up and so did Cingular. They told me that Motorola has had lots of problems with this phone. So Cingular sends me another phone, V551.Well, that was the end of line for me. Even with this phone, which was supposed to have all the problems fixed of V600, it is slow to response, and loses connections to the service. I know its not cingular problem, because it does show that i have 4 bars of connection. Its just, it doesnt want to work.This was my first and Last Motorola phone. I WILL NEVER BUY Motorola crap again.
