In a surprise move, Apple has released iOS 5 Beta 5 (build 9A5288d) to developers on Saturday. Apple typically releases new developer seeds on weekdays. Alongside the iOS 5 beta 5 release is Xcode 4.2 Developer Preview 5, iTunes 10.5 Beta 5 and Apple TV Software beta 4.
iOS 5 Beta 5 is available as an over the air update, but according to the release notes, users must first erase all content and settings by choosing Settings > General > Reset > Erase All Content and Settings. Apple recommends backing up your device using iTunes 10.5 Beta 4 or through iCloud prior to installing iOS 5 beta 5, and subsequently restoring. That said, some users have been able to upgrade fine without going through that process.

It's almost as if they are trying to do some sort of "beta testing" with it or something. Crazy Apple!
The term "beta tester" has sure changed a lot from when I used to do it.
There is a difference between being compatible with iOS 5 and having features that require iOS 5. I am the developer of an app that does not run at all on iOS 5 at the moment. However, I can fix the problem and make it work on (a.k.a. be compatible with) iOS 5 without ever touching the iOS 5 SDK. I can submit that update today. The thing I can't do is submit an update that uses an API that is only found in iOS 5. These apps that have updated for compatibility with iOS 5 are doing the former: fixing issues with running on iOS 5 using the iOS 4 SDK.
Are your talking about OS X Lion?

It's a beta. The only officially supported OTA updated with be starting with future versions of iOS 5.0 onward. They don't really care about bugs that only arise from 5.0 beta 4 -> 5.0 beta 5.
