Following up on the announcement that Apple will release a new version of the iPhone 5 to support T-Mobile’s network, the company has clarified that unlocked current-generation iPhone 5 models will work on T-Mobile’s network—partially. According to a report, the original iPhone 5 can connect to T-Mobile’s HSPA+ 21Mbps and LTE networks, but will not work on the company’s newer HSPA+ 42Mbps network.
Due to cellular radio frequency differences that apparently vary from city to city, it’s impossible to know for certain what current iPhone 5 speeds will be like at a given location within T-Mobile’s network. This issue is being resolved with the new iPhone 5 model, increasing the chance new customers will be able to connect at better speeds.
