found it very useful and easy to follow:

but unfortunately, it doesnt seem to work for me. I installed and got everything to work fine (i think) since the gnubox app background color turned blue, however, when i start my mini opera browser and choose access point "bt" (as set up for bluetooth internet, it returns error that there a problem with the connection.

Also, can you tell me how to pair 6600 with laptop, in 6103, there is an explicit option to pair devices, in my 6600 i cannot find any such option.

Thanks, looking forward to help.
