Clever girl. They're expanding their iPhone-friendly 3G HSPA+ network (or 4G, as they like to call it) to cover Moscone Center West, just precisely the location of Apple's 2012 World Wide Developers Conference (WWDC) next week. A 9to5Mac reader noticed his iPhone light up with T-Mobile 3G when outside the venue, and T-Mobile PR later confirmed the story:
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.
Coincidental my apps. T-Mobile typically runs their 3G HSPA+ network on the AWS bands, which Apple has not yet deigned to support on the iPhone. That means the million plus unlocked iPhone owners on T-Mobile typically enjoy EDGE 2G speeds and nothing more.
Since their merger with AT&T failed to go through, however, T-Mobile will be getting a nice chunk of frequency, and they'll be using it in part to get on the iPhone's 3G good side.
International iPhone owners attending WWDC, like yours truly, will also benefit. We roam on both AT&T and T-Mobile, though we're typically stuck on 2G when on T-Mobile like everyone else. Being able to jump to 3G will be much, much more convenient.
It's also worth noting, T-Mobile has some cheap pre-paid plans, so if you're in an area that suddenly jumped to 3G, it might be worth considering.
