A cab file for your ppc is the equivalent of an executable (.exe) file on your PC. They are used to install programs onto your device.

Instructions:
1. Download and save the cab file from your PC (skip to step 4 if downloading the cab file from your Saga)
1. Connect your device via ActiveSync
2. Copy the cab file onto your Saga
3. Unplug your device from your PC
4. run the file from your phone to setup and install Internet Sharing
5. Navigate to your start menu and click the IntShrUI icon
6. Select appropriate connection type and Network Connection (USB and Broadband Access for me) and click Connect
7. Now plug your usb cable into your Saga to enjoy your phone's internet connection on your PC!

note: if the above doesn't work the first time around, a soft reset of your phone should solve the problem.
