With Apple pushing out the latest version of iOS, taking the current release to 5.1.1, users are once again split right down the middle, thinking whether or not they should update to the latest firmware.Ultra S

On one side of the fence are the everyday users who use their iPhone without any modifications, but on the other side are the jailbreakers and unlockers who are always understandably hesitant when the update notifications come through.

For those using their devices in line with Apple’s intent, there should be no hesitation in applying the latest iOS 5.1.1 update, however, jailbroken users and those who require a software-based unlock – as always – should refrain from jumping on the iOS 5.1.1 bandwagon until the dev teams give the all clear sign. iPhone 4S users who are currently benefitting from a hardware-based network unlock using the GEVEY Ultra S interposer, the news of the iOS 5.1.1 update may have cast you into a quandary.

If you are one of those aforementioned GSM iPhone 4S owners then worry not, as AppleNBerryhave confirmed via their official Twitter account that those users are safe to update their firmware to the latest version without fear of losing the ability to use the device on any network.

One of the great features of going down the Ultra S interposer route is the fact that the solution does not require a jailbreak, something which delights iPhone 4S owners because at present, there is no jailbreak available for the iPhone 4S running on iOS 5.1.1. Those of you, who may not be familiar with this method, the GEVEY interposer makes use of an exploit that allows the iPhone 4S to be fully unlocked.

With the latest generation of the GEVEY SIM, unlocking the device at hand doesn’t get any more simpler than this, simply fire up the device with the SIM card of your choice along with the GEVEY SIM Ultra S and you’ll be unlocked in a matter of minutes. The fact that the device does not need to be jailbroken is obviously a huge benefit to a lot of potential unlockers, meaning that in situations such as this when no jailbreak is available, those users can still benefit from the latest features of iOS.

Once again, for those who have been using the GEVEY Ultra S GSM interposer for an unlock on a GSM iPhone 4S, an update to iOS 5.1.1 is perfectly safe.
