If you have an upgrade available this year you may want to consider getting it through Best Buy. They’re offering a $50 gift card to anyone who upgrades their cell phone in 2012, but it isn’t without a catch, natch. You have to sign up by February 12th to be eligible, but after taking care of that you’ll be in line to receive a gift card whenever you upgrade your phone at their stores. You might as well sign up even if you don’t know how you’ll be upgrading yet. Get started here.
