[Developers Only] iOS 5 beta 2 Build 9A5248d is now available for download from Apple's developer site. If you are a paid ($99/year) dev, you can sign in with your developer credentials to gain access to this beta.
The beta is, as always, released under the terms of Apple's NDA. For that reason, enhancements, APIs and features are not listed within this post.
iOS 5 beta 2 build 9A5248d includes the following changes:
Wireless syncing has been enabled for Mac OS X computers (requires 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.
