While the new iPhone 6/6+ looks awesome, it is way out of my price range. Those who have done the iPhone song and dance for a while, in your experience when is the best time to buy the previous generation iPhones for the lowest price? Currently, I am still using my iPhone 4 which I have had for years. I would love to upgrade to something that isn't so slow, but I want to do it when the price is right Oh and keep in mind, I would be buying the phone unlocked. I am not on a contract plan.
