Tether 9700 with ATT to Ubuntu Linux. (modem 3G mobile cell)
 

This how I successfully tethered my BB bold to my Acer One Aspire netbook running Ubuntu Netbook Remix 10.04 LTS Lucid Lynx.

Download barry software for free at SourceForge.net Using Synaptic did not download the peer scripts and also started complaining about dependencies. The Sourceforge .deb files did the trick. I think you only need barrylib0 and barry-util files.

Create the 2 files at the end of this post.

Remove and replace the battery in your phone. Do ask me ... sounds like magic but I read this on several posts and it might have helped. Can't hurt.

Connect the BB via USB cable. Press no for "Mass storage " question.

run the following command in a terminal
sudo pppd call my-blackberry

You should see a lot of modem commands scroll by and eventually stop. Don't close this terminal, it will kill the connection. Type CTRL-C to kill the connection. Open a new terminal tab and type ifconfig In the listing you should see a ppp0 entry showing a successfull connection.

Happy browsing.
