    Based on my experience, I don't rcommend any specific OS. I had to try them and test them until I'm satisfied with the one I want. There is plenty of choices for 7.0 OS and 7.1 OS posts in the forums including instructions on how to install them.

    Happy testing.

    I think any OS you install will have its pros and cons. I'm on the official Tmo .284 and for sure it is buggy but installing a leak will not fix the problems that annoy me per comments on this site. So for now I'm just going to stick with it.

    My issues are mainly with volume levels in the media player and notification sounds while listening to music.

    Try them and find out for yourself. What works for me may not work for you.

    I've tried them all. For me, the best OS which gave strong Radio signal and decent battery life is 7.1.0.391 but I used the Radio file from 7.1.0.318

    For tmo users what are you guys using? My 9900 will be here Thur, and I've read that 391 is solid, and 428 I believe. Not many reviews on the 437.

    7.1.0.402 worked great for me, that being said I'm currenlty on 7.1.0.428 (as of yesterday afternoon) more because I was experiencing issues with my browser connection and thought an upgrade would solve (the problem seems to be a BIS issue actually).
