Like the look of this newer version. Anyone got any idea when its on Orange for upgrades?

According to the mphone site (http://www.mphone.com) its due in May, though i imagine an orange release will be shortly after this as they do tend to wait a little while before releasing it.

They certainly did wih matrix phone and 6210 who's earlier versions seemed plaghued with problems on other networks prior to orange release.
