[Bluez-users] Bluetooth Init Script with automatic Handy detection.

[nospam02@van-schelve.de]

Hello together.

Maybe someone of you are interested in my solution about how to make
a gprs connection over a bluetooth connection to a mobile phone.
Round about 10000 Users in our company are working with it and
allthough they are using bluez so Thanx to all developers for their
well done work.

If any suggestions or questions, you can sent me a mail.
