Finally got round to getting this sorted today! Work perfect, massive thanks to Mattaustiin for the solution. FYI - how I got it to work... - Turn wireless off on Nexus 7 (N7) - Pair devices via Bluetooth - Under 'settings' on BlueVPN (N7) select access point and enter the APN found in the N9 under settings> Internet Connection > Edit Networks > *your mobile internet network* (in my case its - general.t-mobile.uk) - In BlueVPN select the paired N9 device (it will start to show its trying to connect) - When the big 'power' style button comes up on BlueVPN you are connected! Mountains of WIN!
