Bluetooth tether for dial-up networking: Android tablet (client) to Blackberry Curve 3G (host)

Develop an Android App which will connect a Android tablet (in this case a Viewsonic g tablet with android 2.3) to a blackberry phone via bluetooth and tether allowing the Android tablet to use the internet service provided by the blackberry's 3g internet service. This will need to work as a linux script first, then develop an android app which allows the user to connect or disconnect from the tether connection. some of the linux scripts I am using to try and achieve this are: "pand" and "pppd" here are some pages which I have been using to attempt and create the scripts: <[login to view URL]> <[login to view URL]> <[login to view URL]> <[login to view URL]> <[login to view URL]>
