I appreciate that Beta 2 is nice, but this is about it NOT being released for OS2008, or the n8x0s.
@Roth, Raven, Cincibluer6, Mobiledivide: Have you all installed firefox 4 on an n800 or n810 running OS2008? If so, how? If not, then this is not the place to discuss how well it's working on your device, this thread is about getting it to work/why is it not being released for OS2008.
