Enable Internet Connection Sharing Wifi and Modem Tethering on Windows Phone

After Mango Update ( 7.5 ), I was expecting Windows Phone ( Samsung Focus Unlocked AT&T ) to have Tethering enabled like Nexus S had so I can connect with my laptop or any other phone to share internet connection but it seems because of restrictions by operators it is not possible.

Then I cam around two hacks One  which allows you to enable USB Modem tethering so you can connect it to PC as Modem and second allows you enable Internet Sharing feature ( or using WiFi as portable router ) in Windows Phone 7.5 on available Samsung devices.

Warning : Both the tutorials are unofficial, So make sure you have data backed up or be ready to install the apps again using Zune or Overt The Air.

Update : If you are using a Samsung Windows Phone, Use this Six Step Method to get Interop Unlock and Wifi Hotspot
