Having just cleared the FCC gauntlet, the Moto RIZR Z3 is set to launch on T-Mobile on March 12. The new version will feature a 2-megapixel camera, music playback, stereo Bluetooth, quad-band, speakerphone, voice recognition and a 220 x 176 resolution display.
It has not yet been announced how much the RIZR Z3 will sell for, but given the proximity to launch, I’m guessing we’ll know soon.
The motorizr z6 is the one based on linux. The z3 is still (as far as I know) based on the older proprietary OS, similar to the RAZR and PEBL and so on.
