Apple iOS 5.0 Beta 2 Intro Logo on iPhone 4 HD

Apple just released iOS 5 beta 2 to developers. Build 9A5248d is available now in the Dev Center for registered iOS developers.
Apple has just released the second beta of iOS 5 for developers.
The biggest new addition: Wi-Fi syncing with iTunes 10.5 (also a developer beta released today) is ready to go.We just did a full restore and install of iOS 5 beta so we could test out iCloud's new backup.
All you do is log in with your Apple ID and your phone restores from it's last backup point.
After a quick download, the phone restarts. You have to log in with your Apple ID and all your apps appear in the same place as they were before. They begin downloading right away.
From what we’ve been able to see in the release notes so far, it looks like iMessage on iOS 5 beta 2 won’t be able to communicate with iMessage users on beta 1, and the new iTunes 10.5 beta won’t be able to sync with devices running the old beta 1:
Message seed 2 will be unable to communicate with iMessage users on seed 1.
The version of iTunes that comes with beta 2 cannot sync devices that have the beta 1 software installed.

Summary : 
Apple has just put up the second beta version of its new operating system for the iPhone, iPad, and iPod Touch devices. iOS 5 Beta 2 build 9A5248d is now available for registered iOS developers in the Apple Dev Center. iTunes 10.5 Beta 2 is also available for developers."
