I have been using .52 for 4 days. I am traveling abroad right now, and basically have been communicating back to the States via UMA on T-Mo. Crystal clear, and no problems thus far. I did have to load some background choices of my own, since this version didn't load any, but that is a small price to pay until the official release. Great improvement over .46. MWI is back..HOORAY. I wasn't a fan of Youmail, so this is welcome. Can't wait for the official, but this one is pretty good.
