HTC Touch Sprint?

[ChudaiPati09]

My friend has, I think, a HTC Touch. He got a new phone so he sold it to me.
I was surfing, and I came across an article of Windows Mobile 6.5. I understand that there is no office version out there yet, but there are unoffical versions. I found one called MightRom 6, I wanted to try that out, but when I opened it, the picture of the phone wasn't the right picture.

I was wonder if it was okay to install that on my phone? If not, what ROM can I install that will give me Windows Mobile 6.5?

Thanks
