The word according to mobileburn is that they are looking at ways of porting their new Sense UI, the user interface recently seen on the new HTC Hero, to other non Google Android mobile phones.
It has been hoped that the Sense UI could end up on the T-Mobile G1 or even the non Google branded Magic on Canada’s Rogers.
However, apparently it’s not possible due to the same licensing terms which prevented Microsoft Exchange clients on “with Google” branded handsets, so this also applied to the T-Mobile myTouch 3G as well.
