iTweakiOS Releases Global CarrierCrack for Everyone
This version of CarrierCrack overrides stock cellular radio parameters that dumbed-down older devices, thus enhancing signal a bit. It also opens up FaceTime for certain users who were blocked from using it. It has the potential (depends on if your carrier overrides this or not) to open up the 2G/3G/4G/LTE selection menu and the LTE only option.
