U.S. carrier T-Mobile has decided to offer “additional support” to customers using the iPhone on its network, reports TmoNews. While T-Mobile doesn’t sell the iPhone, it reports that more than 1 million unlocked iPhones are used on its network and the additional support will be useful to T-Mobile’s less tech-savvy iPhone users.

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.
