Well, that didn’t take long. In light of yesterday’s Verizon announcement heard ’round the world, T-Mobile has crouched into defense and released a commercial making the case for its own network in light of both AT&T and Verizon possessing the iPhone 4. And that would be? Their networks are still slow. That’s one point we can’t dispute from our own own tests with T-Mobile HSPA+ and AT&T 3G, but we still suspect T-Mobile wishes it has a piece of the Apple pie.
