Okay I've been using for over a month and wanted to give an update.
Still everything working well. Battery life etc no issues. I still have the magnetic sensor error in smart tools app but this has not affected navigation nor maps.
My only gripe was the Internal SD car filled up too quickly with all the apps I wanted. So reading Brunos thread @ XDA I saw there was un update to both the ROM and a way to disable the Internal SD.
I took the big step last night and it worked. You need to install SP Tools and you need drivers for the phone to 'scatter the internal memory' The new ROM from Bruno 3.1was installed with Aroma. A very neat system, I now have more internal memory and most apps can be moved to my external SD card.
So in summary. A great phone, but If like me you have loads of apps you may have to disable the Internal SD card as it is too small. All details over at XDA.
