I had the same problem as someone else (sent a few pictures, then it broke... sending a picture causes white screen and a "reboot"). Tech help thinks it might be because we had an old 32K SIM card.Enabled bluetooth and in the process it starts asking for passcodes, etc. Tried to change the default from 12345 to my zip code. Bottome line, by the time I was done with the stupid menus, and seen enough CODE ERROR messages, it locked me out and DESTROYED my SIM card. Had to get a new one and rebuild ALL my data. Not happy.Moving from a Motorola to a Samsung was pretty easy, functionality and keypad-wise. Moving to a Nokia is WEIRD. Don't like the layout at ALL.Now to the good stuff. The camera component is probably the best camera on any cell phone I've used or seen to date. Not as soft or blurry as our Samsung. Very bright and clear displays, inside and out--very high resolution. Has a very capable night vision mode (could be what hosed up the picture send capability after a few days, who knows?)Based on the problems I had, similar to others, I'd rate it 2 stars. But if that was a SIM problem and the replacement works fine, I'd give it 4 stars because of the quality of the camera. So it gets 3.
