Some time ago, 9to5Mac reported that Apple was looking into opening up the iOS beta program to the public. Doing so would allow for more feedback coming from users, regarding bugs and other problems within the firmware.
The public version of the iOS 8.3 beta 3 firmware can be downloaded from the Apple Seed website. After signing in with an Apple ID, users hoping to test out iOS 8.3 before its public release are required to download a configuration profile. This profile will allow users to successfully download iOS 8.3 and future updates.
iOS 8.3 ships with the new Apple Watch application, which cannot be deleted or removed from a device (just like any native app). The new firmware also brings a filter for messages, allowing users to 'Report Junk' when receiving a text message from someone not listed in Contacts. We expect the full release of the firmware to be available for download some time next month.
