First, I tried out the 1st method called iFonz. It looked lame, was slow and overall, well, lame. :)
Turns out the OS i got is a cooked ROM (hybrid OS basically) that has mixes of Windows Mobile 6.1 Pro, HTC OS and a few other hacks. I added a few more features of my own such as:
-iPhone dialing pad
-iPhone-like on-screen keyboard
-iPhone slide-to-unlock screen lock
Basically I like iPhones. :P but this OS isn't all that bad. It runs mainly on the Windows OS which I don't hate near as much as the Windows PC OS (yes, I know about Windows 7 but Leopard and Snow Leopard still lick it!) and it is actually fairly easy to navigate the UI with your fingers instead of the stylus.
Here are a few screenshots:
