iOS 5 Beta 2 was released and brings Wi-Fi Sync

Apple has just released its second private iOS 5 Beta 2 for the upcoming iOS 5, and will bring some brand new features and improvements, including a revamped notifications system and tight integration with the new iCloud.

The iOS 5 Beta 2 is available only for registered iOS developers and has been released along with the a second beta for iTunes 10.5. The new iTunes update is crucial for testing the wireless syncing via the iCloud, but the developers will also need the pre-release version of Lion or the most recently available Mac OS X 10.6.8 update.

“WiFi Syncing

In iOS 5.0 beta 2, wireless syncing is now available for the Mac. It requires iTunes 10.5 beta 2 and OS X 10.6.8 or Lion. You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.

Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings -> General -> iTunes Sync (same network as paired computer required). Be sure your device is plugged into a power source when performing Wireless syncs.
If you find issues with apps, media and/or photos synced to your device, you can reset then resync. From Settings -> General -> Reset, choose Erase all Content and Settings. Then reconnect to iTunes and sync again.“

In this beta, iTunes may incorrectly report Photos as “Other” in the capacity bar. Photo syncing otherwise works as expected.

Also, you should know that once the iOS 5 beta 2 is installed, it cannot be downgraded back to earlier versions. It just have to wait until the later betas or the final version will be available and delivered over-the-air.
