iOS 5 Beta 3 Available to Download
Apple has released iOS 5 beta 3 for developers to download, the build comes as 9A5259f and supports iPad 2, iPad, iPhone 4 GSM & CDMA, iPhone 3GS, and iPod touch 3rd & 4th generations. Apple TV2 has received a separate update, however it is still not considered iOS 5.
Alongside the latest iOS 5 beta comes a new version of iTunes 10.5 at beta 3, which seems to be required to sync iTunes with your iOS 5 beta 3 devices.
You can download the latest beta directly from iOS Dev Center, as usual you will need an active developer ID to access the files.
