The Nokia 6126 for AT&T and 6133 for T-Mo are innovative new clamshells from Nokia. They are great for the lazies who want a flip phone but don't want to use the extra energy to actually flip it open. The solution: throw on a button on the outside of the phone that will flip it open for you!

But there's more to this nice little handset. It offers MicroSD, MP3 player, megapixel camera, bluetooth and quad-band support for use around the world. The 6133 also adds FM radio.
