An XDA Developers Forum user shared a step-by-step guide for brute-forcing his way into the internet sharing feature of Windows Phone Mango. The guide helps you enable the internet sharing feature with carefully tuned registry keys on legacy Windows Phone Mango devices like the Samsung Omnia 7.

This hack proves at least two such devices, the Samsung Focus (US) and Samsung Omnia 7 are already capable with driver support presumably added in the Mango update.

After deploying a handful of homebrew XAPs, dialing Samsung diagnostic codes and a few long breathes during restarts, "internet sharing" finally popped up the settings dialog. A quick flick of the "on" toggle, lo and behold, it actually works!

Windows Phone Hacker posted a simpler version of the original guide (right under) which utilizes an updated homebrew application that has the hack built-in.

According to Windows Phone Hacker to get WiFi sharing enabled on your Samsung Windows Phone:

  1. Download DiagProvXML and Samsung Tools
  2. Deploy both XAPs to your phone
  3. Run DiagProvXML and hold down on the Internet Sharing item, press Execute
  4. Close (press Back) DiagProvXML, and run Samsung Tools. Press Apply to set Auto Data Config.
  5. Your phone will reboot, and everything should work from there on it.

Here is the video walkthrough:

The xda-developers forum guide is right below:
