While upgrading coverage inside the West side of the Moscone Center, T-Mobile has also deployed 4G HSPA+ service in the 1900 MHz band to test the live network on a small scale. As part of the company’s previously announced $4 billion network modernization effort, T-Mobile plans to launch 4G HSPA+ service in the 1900 MHz band in a large number of markets by the end of the year, which will make our 4G network compatible with a broader range of devices, including the iPhone. NOTE: The time and location of this test is just coincidental.
So if any of you guys that have plans to attend WWDC next week and you happen to own an iPhone on T-Mobile’s network, do not be surprised if you discover that you suddenly have a 3G signal on your phone.
