Today, Apple has seeded iOS 6 beta 2 to Apple developers. If you are already on iOS 6 beta 1, you can update to beta 2 OTA by going to settings>general>software update. The OTA update is 299mb, otherwise you can download the full IPSW from your developer portal to restore with iTunes.

The update includes some bugfixes as well as new functionality. We must stress once again that this is for developers only, while iOS6 is still in beta mode, it will be very buggy. Only developers who wish to start adding iOS6 functionality to their App Store or 3rd party apps should be installing this firmware. The firmware can be jailbroken, but Cydia will not be installed with the jailbreak since the SDK has not yet been updated to support iOS6.
