FCC documents revealed information about new phone from Samsung, coming to Sprint PCS the SPH-A900. The FCC documents doesn't show much about it but some low-res pictures reveal that it is a thin clamshell device with internal antenna, with design, resembling the Motorola RAZR line. Sometime ago there were some rumors about Samsung Blade phone, and it seems that the SPH-A900 is actually the Blade. The pictures show that the A900 is a pretty thin clamshell with swiveling camera (probably a megapixel unit), featuring music player with music-dedicated keys on the front cover.
Still there is no official announcement from Sprint, but there are already some live pictures, and receiving a FCC approval means Sprint can launch it soon.
