I'm on EE/Orange, a Nexus 7 running cyanogenmod latest nightly, and an N9 that is open, incepted, etc. No ppp widget. BLueVPN works for me. I had to enter some info after i connected the two together by bluetooth. In BlueVPN i had to go to the Settings menu, tick the Bluetooth Insecure Socket box, have *99***1# in the home number box, and have "orangeinternet" in the Access point box. Authentication is left as "password authentication". Then i had to EXIT BLUEVPN, not minimise but EXIT using the exit button, and then run it again, and then connect them together. Now, it works every time. If an app, like say the mumsnet app, wont use BlueVPN's net to connect, i can usually use Chrome to access the site, rather than using the app, and it'l work well enough - though Google play will only let you browse, not download anything.
