Upgrading to iOS 5.1.1 or not has been the question by many since Apple`s release of the new firmware yesterday. Those on tethered jailbroken iOS 5.1 can use RedSnow to tether jailbreak iOS 5.1.1, while users on untethered jailbroken iOS 5.0.1 are warned against upgrading since there is currently no untethered jailbreak for iOS 5.1 or iOS 5.1.1
The same questions is posed by unlockers, do we upgrade or not? It`s simple, if you are on software-based-unlock, don`t upgrade, but if you are an iPhone 4S GSM user currently unlocked using the hardware-based-unlock Gevey Ultra S interposer, go ahead and upgrade to iOS 5.1.1,you will not lose your unlock status.
ApplenBerry on Twitter today has given the green light for iPhon 4S GSM users to upgrade to iOS 5.1.1 which will not affect their unlock status.How does that work? well, Gevey Ultra S doesn`t require jailbreaking which is an added feature for those who don`t care for jailbreaking or in cases of no available jailbreak. Gevey Ultra S uses an exploit that fully unlocks iPhone 4S.
Again guys, if you have an iPhone 4S GSM unlocked using Gevey Ultra S interposer, you can upgrade to iOS 5.1.1 and keep your unlock status.
