Apple just set the iOS 6 beta page live, and we're hurreidly downloading our build 10A5316k install images. Interestingly enough, Apple has decided to call the iPad 2,4 "iPad 2 Wi-Fi Rev A" which is a decidedly more human name, if a bit confusing. The iPhone 4S image weighs in at around 880 MB.

We'll update with some impressions and screenshots after getting it installed. iOS 6 includes numerous improvements to Siri, Facebook integration, as well as Apple's own mapping product, and will launch sometime this fall.
