AppleNBerry, the official Gevey SIM online retailer has tweeted this:
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?
Please keep in mind that Gevey Ultra S is an unlocking solution for iPhone 4S which enables you to use SIM card from any carrier on your iPhone 4S. But, it’s not a jailbreak solution which means you cannot run any jailbreak tweak or app such as SBSettings, Winterboard and others
AppleNBerry has also mentioned that Ultra S can unlock iOS 5.1.1 on GSM iPhone 4S only. CDMA iPhone unlocking with Gevey Ultra S requires your iPhone to be jailbroken – which is not available for iOS 5.1.1 yet.
The fact that the Gevey Ultra S can unlock GSM iPhone 4S, without any need of a jailbreak, is a huge benefit to a lot of new unlockers, because users can benefit from the latest iOS even if there’s no jailbreak available for it.
