Apple has just posted its second private beta for the upcoming iOS 5. The major update was first unveiled back at WWDC 2011 and promises a slew of much requested new features including a revamped notifications system and tight integration with the new iCloud. The final release of iOS 5 is expected for this fall.
The second beta for iOS 5 is available only to registered iOS developers and has been released along with the a second beta for iTunes 10.5. The update iTunes is important for testing the new wireless syncing via the iCloud. There are a total of nine distributions of iOS beta build number 9A5248D, which includes three for the iPad 2 (WiFi-only, GSM, CDMA), one for the original iPad, two for the iPhone 4 (GSM and CDMA), one for the iPhone 3GS, and two for the iPod Touch third and fourth generations.
To fully test the new iCloud wireless syncing, developers will need to have the iTunes 10.5 update along with the pre-release version of Lion or the most recently available Mac OS X 10.6.8 update. However, it's noted that once the iOS 5 beta 2 is installed, developers cannot downgrade back to earlier versions. They can only upgrade to later betas or the final version, which may all be delivered over-the-air.
