The fight for smartphone owners is netting us all some pretty good deals

There's a lot of poaching going on in the wireless industry right now. And that makes it a pretty fun time to be a consumer.

Sprint and T-Mobile are in pretty close running to be the nation's third-largest wireless carrier -- a title Sprint currently carries, though both significantly trail Verizon and AT&T in terms of size. That may explain why they're going after each other with such gusto. Ultimately, that's a good thing for customers, who reap the benefits of the competition. But stealing customers from each other isn't the only avenue for growth.
