I went from .78 to .100 and the only real issue I have is memory leak. After a battery pull I have 50 meg. 24 hours later it is down to 38 meg. Thats with just the basic apps running. The phone starts to slow down. Also some screen presses don't respond and need 2 or 3 tries to finally respond. Battery life is not as good as .78 was but its nowhere near dire.
Has anyone had VSOD? I have .99 and like it besides that it is a little slow. I thought about upgrading but I read about the VSOD and I don't want to go down that road again. I had the same issue with .86 and .90 but .99 has been pretty smooth (except slow typing and memory leak)
