Just a quick note that Apple released iPhone OS 4.0 beta 2. There is not much known about what new features Beta 2 has in store for us, but we do know a view little things.

1. The time for task completion has been changed from 5 to 10 minutes.
2. Beta 2 probably fixed a lot of bugs but also got some new bugs, for example, it doesn’t save screenshots and freezes when you tak a photo.
3. Mail accounts now have small icons next to them.

OS 4.0 beta 2 “355 MB” can be download by developers at developer.apple.com.
