The HTC Inspire 4G is part of a new effort on AT&T's part to pad out their lineup with some top-flight smartphones, a smart move now that the iPhone is no longer exclusively theirs. What's especially notable about the Inspire is that it's AT&T's first "4G" phone, running on an HSPA+ network that AT&T promises will deliver super-fast speeds--but what AT&T isn't rushing to tell you is that you probably won't see those speeds yet, even with a 4G phone like the Inspire. All over AT&T's website is an asterisk after mentions of 4G, leading to a note saying that 4G is "available in limited areas." Take that seriously, folks. No one knows where those "limited areas" actually are, and if AT&T does, it's not telling.
