The gold master (GM) seed is now available on the Apple Developer website, but remember you cannot update via OTA for a GM seed. With previous gold master seeds, a developer accounts not needed to install iOS, however we have not tested this on iOS 8. Either way, we recommend you wait until the official release on September 17.
The new GM build is 12A365, while the previous seed was 12A4345d.
Here's a few of the new features in iOS 8 that we've already posted: Continuity, Handoff, AirDrop, Instant Hotspot, Health, iCloud Drive, Family Sharing, Photos, Camera, Mail, Safari, Messages, QuickType, Third-Party Keyboards, Interactive Notifications, Spotlight, and Contact Shortcuts.
Apple also announced the iPhone 6 and iPhone 6 Plus, as well as Apple Pay and Apple Watch today at its event.
