Now that Apple's event has all but been confirmed for September 10, it's time to think about your next hardware move. That is, what you're going to do with your current iPhone and iPad when the iPhone 5S and Retina iPad mini get announced at the rumored Apple event — which is less than a month away.
This chart from NextTrade shows the trend of iPhone and iPad prices after a new Apple product announcement, and it isn't pretty.
I priced my current iPad mini (64GB, Verizon LTE, in perfect condition) and got the following quotes:
Amazon requests that you mail your device in within a week (although its policy allows up to 25 days), but Gazelle and NextWorth offer a more generous 30-day mail-in window.
9to5Mac notes that prices are certain to fluctuate in the run up to September 10 (as in down) and has the comparison charts from the big three buyers above and Gamestop and Best Buy. 9to5 also notes that Mobixa is offering slightly more money than the vendors above, although it's only buying iPhones (not iPads) at the moment.
In short, if you have any inkling of selling your iPhone or iPad next month, it costs you nothing to lock in your trade-in price now. There's literally nothing to lose.
What are you doing with your old iron on September 10?
