I dont understand, does that mean this version of Andriod on the chiense phones is not the same version as on phones such as HTC?
it runs android at its core, but each manufacturer will tailor it differently for their own phones - ie optimize it to run on the processor they are using, fix it to run nicely with the screen resolution present in their phone etc.
the android that runs on an HTC phone wont run on another phone - however most apps developed for android should run on all phones that run android. some apps might need recompiling first.
what raz is rightly saying is that sciphone are unlikely to release many (any?) updates to fix bugs and add new features to their android phones, whereas HTC certainly will.
