In June of '04, I purchased the V600 when switching from ATT to Cingular. My old Nokia 6500 series worked just fine, and the service was satisfactory. Since changing phones and service, the V600 was replaced, replaced again, recalled and replaced, and finally replaced for the fourth time with a Motorola 551. (I will be reviewing that one also.)I cannot even count the ways that I hated the V600. No electronic device, especially a phone, should cause someone to cuss out loud at least a half a dozen times each and every day. I don't care if it can take a picture or walk the dog. I want it to answer when the time comes to answer. I want the ringer to work when and how I choose. I expect it to start dialing when I start pressing the keypad. The V600 didn't do any of these things consistently...and there were a whole host of other maddening quirks that drove me to the aforementioned cussing.Buyer beware.Oh, and I also purchased the Motorola HS810 bluetooth headset. It now drops a call and needs re-charging after about 10 to 15 minutes.
