Once you know you're getting an iPhone and now, you need to decide which iPhone you want to get. While some might consider the the latest, greatest iPhone 5s a no brainer when it comes to their next purchasing decision, others might think the funner, less expensive iPhone 5c, or even the hold-over iPhone 4s is a much better value. If you're on-contract, you'll be paying a couple thousand dollars over the next couple of years anyway, so a few hundred for up-front may not matter to you. However, if you don't have that couple extra thousand up front, especially if you're going off-contract, up-front cost really will matter. It's important to really run the math on this and see what suits you best. So, premium, popular, or passé, which one should you get?
