For those who live in Namibia, they may be experiencing the same handicaps as myself. Many default options do not include this country (which happens to be geographically four times larger than the United Kingdom) when setting up broadband connections. However, I decided to experiment and setup my Sony Ericsson W890i as a broadband device. And it worked. It is pretty simple and will probably work for other mobile phones as well.
1. When connecting the W890i via USB it prompts for the kind of connection. Select "Phone mode".
2. Ubuntu Netbook Release will prompt you to setup a broadband connection. Follow the wizard until you need to select the country.
3. Since Namibia is not present, I chose MTN of South Africa.
4. Finish the wizard and test.
Hope it works for you as well.
