If you're planning on copping a T-Mobile smartphone, you may want to wait until this weekend. For the holiday weekend, T-Mobile will be having a "Two-Day All Phones Free Valentine’s Sale", which, as the name implies, means that every single smartphone T-Mobile sells will be available for $0.00. How? Why? We don't know. All we know is that in order to get the free phone you'll have to sign up for a two-year contract, and buy it on either Friday, February 11, or Saturday, February 12.  And, yes, it includes upgrades.
