For the Mobility .419 you have to sign a webpage that says your are a mobility customer. But here are links to it http://forums.crackberry.com/f151/of...bility-410624/ I have been running with it for several months and no major issues other than having to use OPTIONS SMS Text Conversation Style Stripes instead of Bubbles to get rid of lines in SMS display. Not any more memory leaks than any prior OS versions. Seems pretty solid. Still have to do battery pulls every 2 to 7 days to get memory back.
