Difference between Ophone SDK and Android SDK

China Mobile has announced their own version of the online shop, it's dubbed the mmarket. This is the main platform for they new line of phones based under the new Ophone name. As most has suspected the Ophone is really just a repackaged Android platform with a minor tweak. First as of now the Android SDK is up to version 1.5, however the Ophone (after days of this major marketing event and product roll-out), is still sitting at version 1.0. There are a few functions added onto it, it is suspected that these functions are possibly used for the billing since China mobile bills their online payment through their phone bills.
