The new cards Gevey Ultra S launched specifically to decode iPhone 4S terminals are not compatible with the basebands of iOS 5.1 and if you did not want to update to this version of the operating system, then you end up unable to decode the iPhone. Although now the owners of iPhone 4S terminals must be extremely vigilant, in the future we may have cards available to unlock the new version of the operating system, at least that's what Gevey announces. The producers of the famous cases have published a message on their website announcing that they are working on the development of an unlock solution for iOS 5.1, but they do not specify for now which iPhones will be decoded with it.
When will this unlock solution be available? Hard to say... but when I find out new information I will publish it for you.
