Disclaimer: I'm only familiar with the Sprint models.
The Samsung A800 from Sprint has gotten good reviews for it's 2MP camera phone. It's a slider phone (details at
PhoneScoop.com). It's a 2MP camera and the phone has a transflash (microSD) slot. Sprint has a newer 2MP camera on the A940, but that hasn't received as favorable reviews and people are concerned about the swivel screen. The A800 actually has a "camera" format with a large QVGA screen and actually looks and feels like a camera when the slider is closed.
If you're interested drop me a PM. I have one (NEW) I'd like to trade or sell off that I received from insurance (a sub for my older discontinued phone). It's unused, and according to the service code is not reconditioned. It's a nice phone, but a slider isn't best for my usage due to work environment (although I love the camera).
