Per Joseph Brown’s iTweakiOS and Cult of Mac, specialized code exists on iPhones and iPads operating on Verizon, AT&T and Sprint, which limits the devices’ network settings to effectively caps data bandwidth.

Brown took snapshots of the iOS code managing the three carriers’ network settings as applied to an iPhone 5, all of which appear to hamstring the handset’s cellular data capabilities. For example, an AT&T iPhone 5 was limited to HSDPA “Category 10,” which tops out at 14.4Mbps. The second-largest U.S. carrier’s network is capable of supporting up to HSDPA+ speeds that reach 21.1Mbps.

As for Verizon, Brown found throttling code on the telecom’s versions of the iPhone and iPad relating to its 4G LTE network. Sprint, it seems, does not have such limitations enabled for its high-speed data offerings. Apple devices running on the 3G networks owned by both Verizon and Sprint, however, are also affected by similar limitations.

Because Apple is in complete control of the code running all of its devices, it can be posited that the company instituted the bandwidth caps at the behest of its partner carriers.

“[…] from previous statements released by AT&T and many tech orginizations [sic], iPhones are very complex devices with a very complex OS,” Brown writes. “The OS eats much more data, even when in idle mode, than most phones on the market. So by carrier request, Apple limits devices to ‘even out’ the network, even if it means Galaxy users out perform Apple devices by such large scales.”

In his testing, Brown did not find evidence of throttling on devices operating on T-Mobile’s network.

Stay tuned for additional details as they become available.
