Apple said to limit wireless speeds on some U.S. carriers2013-06-06 09:22 by DanielaTags: Apple, iPhone, iPad
A developer who provides iPhone hacks has discovered code in iOS that suggests Apple is helping the top three U.S. wireless carriers throttle data speeds for all iPhone and iPad customers. In a very detailed and long blog post, Joseph Brown explains why iPhones are being "out-performed by Android devices," and why he thinks his recent carrier hacks have been able to deliver increased data speeds. For example, Brown found that 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.
