T-Mobile to Offer Additional Support for iPhone Users on Its Network
T-Mobile will support users who have questions about "common procedures, information about feature and specifications and other basic device questions." Most T-Mobile iPhone users are limited to T-Mobile's slower EDGE network due to the iPhone's incompatibility with the 1700/2100 MHz bands used by the carrier for its faster data networks. Late last year, though, some of T-Mobile's towers were adjusted for its faster HSPA+ network, moving them to the iPhone-accessible 1900MHz band in some "pockets" of the country.
Earlier this month, T-Mobile claimed the next iPhone chipset could be capable of supporting the carrier's Advanced Wireless Spectrum, but noted that it didn't have any specific knowledge of Apple's future products.
