A website which was dedicated to providing iPhone carrier hacks claims to have discovered code in versions of Apple’s iOS that suggests the nation’s top three carriers are purposely throttling iPhone and iPad data speeds for all customers. According to developer Joseph Brown, operator of iTweakiOS, there is specialized code that exists on iPhones and iPads operating on AT&T, Sprint, and Verizon which limits the devices’ network settings to effectively cap data bandwidth.
Brown has taken snapshots of the iOS code that is 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 14.4 Mbps. The second largest U.S. carrier’s network is capable of supporting up to HSDPA+ speeds that reaches 21.1 Mbps.
As far as Verizon goes, Brown found throttling code on the telecom’s versions of the iPhone and iPad relating to its 4G LTE network. Sprint doesn’t have 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. Since 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.
Brown mentioned the following:
[…] from previous statements released by AT&T and many tech orginizations [sic], iPhones are very complex devices with a very complex OS. 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 outperform Apple devices by such large scales.
Have any of you felt like your speed has been throttled?
