If Black Friday sales aren't your thing, T-Mobile is giving you the option of doing some shopping a bit early with their Magenta Saturday sale. This one day only sale is being held November 19th in-store only and you can get some decent deals on a BlackBerry with a new service agreement. Some of these deals include a Bold 9900 for $49.99 down payment after $150 mail-in-rebate, Torch 9810 for $49.99 down payment after $100 mail-in-rebate, and the Curve 9360 with no down payment after $50 mail-in-rebate.

Confused by the term "down payment"? Well, it appears T-Mobile has switched up the way they sell devices, and instead of subsidizing the cost and giving customers free or reduced cost phones, they do a down payment and monthly payment after that for the term of the contract.

The phones listed above actually work out like this:

• BlackBerry Bold 9900: $199.99 down & $20/mo., total: $599.99; $150 MIR avail.
• BlackBerry Torch 9810: $149.99 down & $20/mo., total: $549.99; $100 MIR avail.
• BlackBerry Curve 9360: $49.99 down & $15/mo., total: $349.99; $50 MIR avail.

So, if you're planning on getting a smartphone from T-Mobile, you end up paying more money by taking their monthly plan, vs just paying full cost for the device up front. If you don't have $600 to shell out for a new BlackBerry though, and plan to do the monthly payments, you might as well take advantage of the sale, and get the down payment money back via the mail-in-rebate.

Full press release and details after the break.
