For the devs and those that broke down and got a dev account so they can get new versions of iOS early - well good news. iOS 5 Beta 2 is now available.
Some quick notes - you need to install iTunes 10.5 beta 2 first on your mac. Then install iOS 5 beta 2.
Key changes so far:
1. It seems a little more stable. The Photo app is not crashing each time I delete a picture on my iPad - not every time but still sometimes - which is much better than beta 1 which seemed to crash each time you tried to delete a picture.
2. Wireless sync now works - It does require Mac OS X 10.6.8
