T-Mobile is rolling a promotion until the end of the year that is dropping prices on most of its phones to $0 on contract. For the next 10 days, you can get your hands on most of T-Mobile's high-end offerings, such as the Samsung Galaxy SIII (S3) and HTC One S, as well as everything in the mid- and low-end range. The Galaxy Note 2 and Nexus 4 are the notable omissions from this deal. This promotion also only applies to T-Mobile's "Value Plans," which separate the cost of phones and plans, that will require monthly installments (usually $20/mo for about 20 months) to pay off the rest of the handset. They end up being a better deal over the life of a 2-year contract, and even more so when you can skip the $200-$300 down payment to start the plan.
Considering that T-Mobile is moving completely to Value Plans starting in 2013, this will be a good push to get new customers onboard with the idea at the end of 2012. If you (or a family member) are interested in any of these handsets, it may be a better time than any to go pick one up before 2013. Check out a full list of devices on sale at the source link below.
