iOS 5 Beta 1 is Available to Download
Developers can now check out all the new fancy iOS 5 features first hand with the first pre-release version of iOS 5 beta 1. The download is accessible to all registered developers through the iOS Dev Center.
iOS 5 Beta 1 comes as build 9A5220p and supports all iPad 2 models, iPad, iPhone 4 GSM & CDMA, iPhone 3GS, and iPod touch 4th and 3rd gens.
Those without an iOS developer account will have to wait for the public release date this fall.
Update: if you’re brave enough, you can install and run iOS 5 beta without a dev account, it is not recommended and could lead to problems.
