then install zip from sdcard

Thank you very much.

What's your experience with the following ROM been?

[ROM][DEC 14 '11] -=TMX SS 4G=- v0.2 [O.S.R.][Dual-Core w/ faux0.2.5r/Trinity S4G] - xda-developers

Is it lightweight? Stock? Why exactly did you pick it over CM 7? Just for the slicker UI? Or are there any other benefits too?

Thanks!
