Due to this problem user of the iPad Air, iPad Air 2, iPhone 5s and iPod Touch and some earlier models saw that their devices are getting completely unused devices. Because of this issue, Apple decided to stop iOS update for these models and keeping the program continue to those who have the latest versions of devices. The final version of iOS 9.3 has come out with such a serious flaw that it has blocked few iPad users. However, the company Apple has responded quickly to the problem, and first they decide to disable the update so that the number of affected device does not increase, and then they will be releasing a version with a solution quickly. Hopefully, these mistakes are not repeated, but the solution has been rapid, as the company like Apple can not afford such failures. According to the reports, the problem occurs during the setup of iOS, that is after downloading and installing the update. At the time of installation of the update, the device asks for the e-mail of iCloud and user password to proceed. However, when you will try to proceed further a pop-up message will arrive, that you can not continue “because the activation server is temporarily unavailable.” So far, the iPad 2 is the device which was most affected by this error. However, threads in the support forums of Apple and social networks shows that the iPhone 4S, 5, 5C, 5S, iPad mini, iPad 4 and as well as the iPad Air also faced this activation problem. In the absence of the official solution, users are indicating device activation through iTunes on the PC. However, there are reports that the process is not effective for everyone.
