Gevey Ultra S does not unlock iPhone 4S with iOS 5.1

Gevey Ultra S decoding Cosmote

  A few weeks ago I told you that the famous Gevey Ultra S decoding cards were launched which allow you to decode an iPhone 4S terminal with iOS 5/5.0.1 installed. Unfortunately, the premature launch of the decoding cards allowed those from Apple to block the unlock exploit used in them and unfortunately in iOS 5.1 these cards can no longer be used. Those from Applenberry announced on their Facebook account that these cards do not work with iOS 5.1, so everyone's recommendation is to avoid updating to this version of the operating system.

  Until then, you should decode any iPhone 4S with iOS 5.0/5.0.1 on any operator in Romania without jailbreaking.
