With the announcement of new Apple products today comes the iOS 5 gold master, or GM, for short. The is essentially the 8th version of iOS 5 released to developers, and is the retail-ready model — in other words the “golden master”. The new version of iOS 5 launches publicly on October 12th, however developers get the download today (like me). The usual dev tools like Xcode and iTunes 10.5 will also have GM versions ready for iOS 5, all at Apple’s developer portal. The update is not available as an OTA however — in order to upgrade you’ll need to use iTunes one last time.
