This is a great phone. However the way in which Amazon and Cingular offer these phones is a huge ripoff. Read the fine print very carefully, if you break any part of the service agreement, Amazon charges you full price for the phone. This includes trying to port your existing number to the new phone, adding family members to your plan, or swapping the sim from your spouses phone.Existing Cingular customers on family plans currently off contract going month to month get bit the worst by this offer. I managed to actually get hold of a phone specialist at Amazon customer service, and she as much admitted to me that Amazon makes a ton of money off of this from people who don't read the fine print.I urge both Amazon and Cingular to stop this deceptive practice. I've been a Cingular customer 5 years now, yet I can't get a deal like this on a phone.
