Last but not least, a hacked carrier update for Sprint-powered iPhone handsets has become available, allowing iPhone 5 users connected to the carrier the chance of improving cellular download performance, jailbreak-free.
This hack enables 1x Advanced and EVDO Rev. B on the iPhone 5 enhancing EVDO 3G data speeds. Though Sprint is limited to EVDO Rev. A, the device itself becomes more open to an increased amount of bandwidth thus allowing for better throughput of data and data connection. Already intact coding within the carrier files also showed signs that Sprint has 1x Advanced support on their network. So, how knows? This may actually enable something new. Throttling code was put in place to limit users to a certain amount of bandwidth on 3G only as well and has now been removed. As for LTE, no throttling codes were put in place to limit users’ bandwidth nor was any band preference coding put into place to limit users on coverage. This won’t increase signal so don’t expect it to like the AT&T version of this hack nor does it increase LTE as it was not limited in the first place.
Methods are available for both jailbroken and non-jailbroken users, and this particular hack is compatible with the iPhone 5 only. Do note, however, that this process carries no absolute guarantee that cellular data speeds will be increased, and remember to back up your iPhone in iTunes before applying the hacked update.
