Mobile broadband connection through gconf settings

[Naveen reddy <naveen mdl gmail com>]

Hello,

I am pasting a code which adds a connection for mobile broadband using system settings(i.e NetworkManagerSystemSettings)
I want the same connection to be added using gconf settings. I want the scope of connection to be user and not system. I know it is possible because the network manager applet 0.8 does that using gconf settings. Please help me either by guiding or pasting a relevent code for that. I will be very thankful to you.

Here is the code which I have writen
