If you have your iPhone 4s service through Sprint, you may have to go through some extra security features in order to jailbreak your iPhone and get these additional applications and features. Sprint
has been known to be a carrier that has extra security features installed on any phone and especially the iPhone 4s and anything that operate on a sim through the factory and ios. They are contracted
by the factory and they are obligated to provide security on every one of their products. You can still get information and find out how to get through these and be able to unlock your phone and its

Many people have been wondering whether it is safe to download an update on their iPhones after jailbreaking it. Based on the iPhone 4 Unlock Experts' website, one must not perform a normal update
after jailbreaking their Apple devices. This will either corrupt or brick their mobile phones and will disable the jailbreak software. Updating it will also permanently change the iPhone's baseband
which will no longer support unlocking. You must disable the automatic update option on your phone and on iTunes to ensure this from not happening. The manufacturer's update will also override the
code of the jailbreak which will render it useless once they detect that you have hacked your iPhone.
