T-Mobile's one-day sale Saturday: Free 4G smartphones!

MONEY-SAVING MOMENT: T-Mobile has an incredible one-day sale in store for people this weekend!

The fourth major carrier has been struggling for an identity ever since AT&T tried to buy them. After the takeover was shut down by anti-trust regulators, T-Mobile kind of went into the ozone. Customers migrated away from them anticipating AT&T ownership, and the company was frozen and didn't want to launch any new initiatives at such a volatile time.

So what do they do now? Offer a sale on 4G smartphones to regenerate some excitement!

T-Mobile will give away any 4G phone in their arsenal on Saturday, Feb. 11 and they have some very nice Androids. But here's the catch: You have to pay for the cost of the phone upfront and then you submit rebate paperwork to get your money back.

Still, I think it's worth it. You're getting a state-of-the-art phone for zilch. As usual, you have to sign a 24-month contract with an early termination fee of $200. But the phone you get for free after the paperwork. It's a real bona fide deal. And their plans are cheaper than other contract carriers to boot.
