I've downloaded and installed, and am using it through headset. It said on this version, it was designed to be compatible with WM 6.1. Given that all various previous versions have given nothing but trouble to get it to work on the Mogul, my expectations really shouldn't be that high. But I am curious to know if I am the only one that is having problem with this version, or are there other people that have better luck than me on the 3.56 ROM. Thanks for all feedback.
