Activate internet tethering on Samsung Focus with Rogers Canada
Disclaimer: All this works today (tested on several phones), but might not work tomorrow…
Warning: After this setup you won’t be able to sync your phone with the Zune software via a cable, only via WiFi. Unless you manually switch back to cable mode (painful). You won’t be able to deploy apps you build with VS2010 as well…
This setup works for the Samsung Focus phone provided by Rogers Canada carrier.
Please note this is for educational only, hoping for Microsoft to activate this feature in the near future… Waiting for that I am not responsible for any damage to your computer or phone.
