T610: Latest SW-Version (O2 Germany)

Hi over there,

can anybody tell me the latest SW-Version for the T610 from O2
Germany?

BTW: Is it possible to disable/change the direct dial button at
the upper right side of the handy (opposite of volume and camera
trigger)? Currently it's a shortcut to the internet, at least at
my O2 T610. Very annoying. And, possibly, __VERY__ expensive.
