The Gevey Ultra S GSM SIM interposer, which allows users to unlock their iPhone 4S handset, is compatible with Apple’s recently released iOS 5.1.1.
Though a software unlock for the iPhone 4S still hasn’t been developed, hardware unlocks – like Gevey SIM – allow users to apply a carrier unlock to their handset quickly and easily, but for a price ($39.99). However, while some might have worried that updating to iOS 5.1.1 would disrupt the SIM interposer, in a Twitter update published recently, ApplenBerry assures its users that the new software version is nothing to worry about.
Here’s the tweet:
Good news! If you are currently using GEVEY Ultra S GSM to unlock your GSM iPhone 4S on iOS 5.1, you CAN upgrade to iOS 5.1.1
