No. I tried searching for touch screen calibration problems, but nobody described the problem I'm having. (In fact, when I search the forum for "manual touch screen calibration" now, the post you made just a moment ago is the ONLY result.)

Read the first post thoroughly. This build/ROM/whatever this is assumes you already know how FRX works and how it's setup.
It's the ROM on page 1 I just downloaded today. The software itself says kernel version 2.6.27.46. I may have logs, but I'll have to look up how to extract them. I read the FAQs for the various "Android on Fuze" sites and the only thing regarding wifi is "It works." Nothing about a 'wifi-nvram' trick... (Again, searching for that phrase returns your above post...)
That's .27.
Please read the FAQ - http://xdandroid.com/wiki/FAQ
As for horsepower, I know this device isn't exactly the "powerhouse" it once was, but if I can use it for instant messaging or what have you, I'll be happy.
Should work fine for messaging. Wifi calling - doubtful.
