Fujitsu is claiming that the Arrows WCDMA model is the world's thinnest phone at a ultra slim 6.7mm. Yeah, that's right, 6.1mm thin. That would make it about 1mm thinner than the Motorola Razr and much lighter at 105g, with great style overall.
Here you can compare the Arrows WCDMA model with the HTC Vivid and Samsung Galaxy S II Skyrocket.
The phone is coated with a peel-resistant and scratch-resistant "ultra tough guard," which should keep your Arrows looking good and hopefully scratch free.
Along with Corning's Gorilla Glass, the Arrows WCDMA will include the new AMOLED display with high definition and capacitive 480 x 800 4-inch touch screen. It will measure 64 x 127 x 6.7mm and feature a 5.1 MP camera, Bluetooth 2.1 + EDR, WiFi, and 1GB RAM / 2GB ROM upgradable to 32GB with microSDHC. It has a 1400mAH battery to power the Qualcomm MSM8255 1.4GHz processor with Android 2.3.5, which I found to be very responsive while I tested it out here at CES
The Arrows WCDMA has cleared the FCC but Fujitsu is still waiting to get a US partner to make it available here. So until that happens, you may want to look elsewhere if you're in need of a new phone right now.
