It's really happening. Starting today, you'll be able to pick up an iPhone 5 with that Magenta hue. T-Mobile's offering the device both in retail and online, starting at $100 plus 24 monthly installments of 20 bucks. You can pick from either of the two monochrome extremes and if you're looking to spend a little less, you can also choose an iPhone 4S or 4 instead. Remember; you won't get the same subsidized pricing from Apple directly, so scroll through the options at the Uncarrier source and ensure that you're ready for that Coachella stream this weekend.
