I installed it, and noticed a few nice things, but it broke my Kindle app (wouldn't show books, just the splash screen, though I could guess were the books were and bring them up if I hit right.) It also caused some bugs in the Market, with multiple force closes and such. It also took a good bit longer to boot, both after install and a reboot. I restored my backup and am back up and running with stock a3.
^this. unfortunate, because it felt "snappier".
Any one been able to get Hulu to work on this version. In alpha 3 I was able to install a modified version of flash and Hulu works great. It wont on this version, if I try to install my modified version of flash I get a "not installed" message.
Thanks
