Motorola ROKR E2

So far as I am aware, this phone was originally intended to be released as a quad-band, and this is what is currently showing for sale (finally) on mobilebee.com. However here on PhoneScoop it is listed as tri-band 900. Motorola's web-page for the E2 is stunningly useless and contains essentially no tech info. Perhaps the 900 version is related to the China release a few months ago, and there are 2 versions on the market?
