Like clockwork after the release of iOS 7 beta 3 iH8Sn0w has tweeted the expiry date of the 3rd beta iteration of iOS 7. According to iH8Sn0w iOS 7 beta 3 (11A4414e) will expire on Thursday August 29th at 12AM (GMT). Those that caught our previous article on iOS 7 beta 2 will realize it was set to expire on Thursday August 8 at 12AM (GMT).
Apple implemented expiry timers on beta firmwares to ensure developers who update to one of the beta firmwares either upgrade to the next beta or the official firmware when it is released. If you do no upgrade to the next firmware version in time your device will be placed in Recovery Mode.
We will keep you updated with more iOS 7 beta 3 coverage when it is available. Until that time stay tuned.
