Support for Samsung Blackjack 2 Mobile Broadband

I am having an issue getting Gnome’'s Network Manager to connect to ATT broadband network through my Samsung Blackjack 2.

I no the service works because if I boot into Windows I can connect just fine and if I put the SIM card into my unused Sierra 881 I can connect with no problem, so I am confident teathering is functional.

I added the following lines to " /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi" so the network-manager applet would reconize the hardware which it does but it will just not connect except for one time and that time it worked GREAT!

Any ideas or advice would be apreciated
