Unlocked Apple iPhone units can test T-Mobile's 1900MHz 4G HSPA+ network at WWDC
$4 billion upgrade of its network and is designed to create a 4G network for the nation's fourth largest carrier that is compatible with a number of devices including the Apple iPhone. The network, when completed, will cover 220 million people in 229 markets, the largest HSPA+ network in the country. The carrier has been hamstrung by its inability to offer the Apple iPhone to its customers and is also late to the LTE party. It is expanding its HSPA+ network in order to have some type of 4G offering until it starts promoting its own LTE network next year. T-Mobile says it already has more than 1 million unlocked Apple iPhone units running on its pipeline.
Meanwhile, workers outside of the Moscone Center have started putting up the WWDC 2012 logo on the outside of the building. The fireworks should start at 10am Pacific Time on June 11th with the keynote speech that is expected to include some big announcements.
