Jay Freeman Saurik is updating Cydia packages to make them compatible with iOS 5, so updated Winterboard for iOS 5 is pushed through Cydia which is available free for download.
Although, Winterboard is updated for iOS 5 but it does not mean that all of its themes are compatible to the latest iOS as well.
To download Winterboard for iOS 5 just head to Saurik’s Cydia repository on your iDevice.
Apple seeded iTunes 10.5 beta 4 to developers which is required for iOS 5 beta 4. This is important to note that earlier beta versions of iOS 5 than beta 3 are not compatible with this latest release of iTunes.
So, to sync with iTunes 10.5 beta 4 your iDevice must be over iOS 5 beta 3 or beta 4. To download iTunes 10.5 beta 4 go to iOS Dev Center.
