Few minutes back we reported that iOS 5 Beta 2 is live and will be shortly available for Download. Now Apple has also released iTunes 10.5 Beta 2 with some bugs fixes and to support iOS 5 Beta 2 activation. Both of the things are only for Developers, So if you are a non Dev Stay away from it.
The iOS 5 beta 2 might got the iOS 5 Beta Jailbreak fixed. So don’t think to update to iOS 5 beta 2 for now. Stay away from the Beta Updates. iTunes 10.5.2 also enables the Wi-Fi Sync to the devices and can’t sync with the devices running on the iOS 5 b1.
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.
