If you live in the US or Canada then the iTunes 10.3 beta is ready to rumble. Automatic downloads and access to your purchase history is limited to iOS 4.3.3 users on the iPhone 3GS, iPhone 4 (GSM only, sorry Verizon subscribers), and 3rd and 4th generation iPod touch devices. Once you meet those requirements, the iTunes in the Cloud beta promises to keep all of your newly purchased iTunes music in sync between devices while giving you the choice to download previously purchased tracks whenever you want at no additional cost. 10.3 beta also brings the Automatic Downloads feature to your apps and books, now allowing you to purchase tomes from your desktop while keeping them in sync with the iBooks app running on your iOS devices.
Naturally, we couldn't help but test it out ourselves from both a Mac and iPhone 4, so click through for our first impressions.
