Well while messing around with Google Latitude I finally had it working for the first time but then my Phone crashed and was Bricked. Stuck at the Android screen when booting.
Anyhow I followed Timmmm's instructions in post 9 here.

Just reboot after step 2 to re set up the Phone and they worked a treat.
So there seems to be a few bugs around but as a Linux user I am starting to like this phone more and more because it can be fixed/modded.
