Many users have noted that Internet Sharing is missing in HTC Mozart, even in the official Mozart Mango (windows phone 7.5) ROM. Fortunately, xda is there to rescue us. A user known as feropont has unveiled a ROM that is based on the official HTC’s shipped ROM and has Internet sharing function as well.
The ROM is also fully unlocked (developer unlocked) which means you will be able to install myriad of amazing apps and utilities that are not otherwise available via Windows Phone Marketplace. The developer of this ROM is already bundling nifty apps like TouchXplorer (a great file explorer), Registry editor and Advanced config (to mess around with various parts of the OS, safely).
So, how to install it?
