Today is the best day to buy an iPhone from T-Mobile

Holiday deals on the iPhone are sometimes underwhelming -- mainly because the phones sell so well on their own that they don't really need any help finding homes -- but T-Mobile's Cyber Monday deal is actually pretty fantastic. For today only, T-Mobile is selling iPhones with higher memory capacities for the price of the lower tier models. Here's what the company is offering:

• Buy an iPhone 6 16GB and we'll upgrade you to an iPhone 6 64GB

• Buy an iPhone 5s 32GB and we'll upgrade you to an iPhone 5s 64GB

• Buy an iPhone 5c 8GB and we'll upgrade you to an iPhone 5c 32GB

Yes, a 64GB iPhone 6 for the price of the 16GB version. That's a $100 savings on the newest iPhone on the block. The other upgrade offers are similarly great, and all told this is one of the better Cyber Monday deals on Apple gear across the web. The deals are only available online -- Cyber Monday, yada yada yada -- so head to T-Mobile's site if you're hoping to score a free upgrade before the stocks run dry.
