A hacked carrier update that has the potential to deliver improved data speeds is now available to iPhone 5 users on Sprint. The modified update, which has previously been made available to devices on AT&T, T-Mobile, and Verizon, does not require a jailbroken device — just a Mac or PC with iTunes.
Like the other updates, this one comes from Joe Brown and Sky Zangas over at iTweakiOS, who have explained how it works:
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.
This update is a little different to those for other U.S. carriers, because it doesn’t improve LTE speed. However, Brown explains that this is because it was never throttled on Sprint like it was on the other carriers anyway. You should see improved speeds on 3G, however.
There’s no guarantee the update will make a significant difference, and if you already have good 3G speeds, the changes could be very slight. But as no jailbreak is required, it’s certainly worth a try. The update is compatible with the iPhone 5 only at this point, but Brown one for the iPad soon.
