To safely and legitimately use any iOS beta firmware on the developer cycle, your device must be enrolled as a development device with Apple. As Apple warns, installing beta software on your device without registration "could put your device in an unusable state and necessitate an out of warranty repair."
Certificate & Provisioning
With these files, you can use iOS App Signer or Xcode to sign and install any app on your device, no jailbreak required. Certificate and provisioning files are provided to our Silver, Gold, and Platinum customers.
Registrations can be delayed due to high demand or system downtime on Apple's servers. In the event of a wait list, customers who purchased the Gold or Platinum packages will be processed first.
Protect yourself from the unexpected. If you purchase the Gold or Platinum package and your device is exchanged under an insurance program such as AppleCare or replaced due to theft within 6 months of your purchase, we'll enroll your new device free of charge.
Full Revoke Protection
Apple can choose to revoke device enrollments at any time. Gold and Platinum members have exclusive access to a full year of revoke protection, which automatically enrolls your device in a new developer account, free of charge. This feature is limited to 90 days for Bronze and Silver members.
Some apps require special entitlements to function properly, such as the Multipath entitlement for the Houdini and Electra jailbreaks. Gold and Platinum members have exclusive access to a custom provisioning file that supports these additional entitlements with an explicit app identifier.
Online Code Signing
Platinum members can use their registration with popular code signing services like IPA Signer, iOS App Signer, Signulous, and AppDB. You don't need access to a Mac or any computer at all.
