PC Mag checked out the SGH-D307 phone from Samsung, here's a quote from their review:

The Samsung SGH-D307 is a quirky messaging phone with neat features but a very perplexing interface. The first double-fold phone to make it to market in the U.S., the tri-band D307 initially looks like a run-of-the-mill flip phone, with a black-and-white display on the front showing a bold digital clock. It's big, at 3.7 by 1.9 by 0.9 inches, but not particularly heavy, at 4.3 ounces. Flip it open vertically and you see a bright, 176-by-220 color display and a very confusing keyboard with many tiny, identical buttons..
