After the modified Carrier Update of T-Mobile, AT&T and Verizon Wireless been released, now Joseph Brown released the version for Sprint customers ensuring much improved speed speeds on the iPhone 5. At the moment, it is only for the iPhone 5 and we have a version for the iPad.
This modification enables Advanced 1X and EVDO Rev. B on the iPhone 5 to improve speed in EVDO 3G data connection. The LTE connection speed remains intact and the users will not notice any kind of improvement in strength or signal range.
This hack Enables Advanced 1x 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 Malthus Allowing for better throughput of data and data connection. Within the intact Already carrier coding files That Also Showed signs 1x Advanced Sprint has on Their network support. So, how knows? This May actually enable something new. Throttling code was put in place to limit users to a Un 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 band nor any preference coding was put into place to limit users on coverage. This will not Increase signal so do not 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.
