It might be a little early to ask this, but: I currently have an iPhone 5c, and I want to upgrade. Should I upgrade to the 6s this September (assuming it does come out then)? Or wait for the iPhone 7? I'm a little worried about my 5c dropping in value even more, so I don't want to put it off too long, but I feel like waiting for the 7 would be more worth it. (The new number usually means new design/physical features, while the letter usually means internal improvements like processor, ram, camera etc. I want the 6s, it'll be here sooner, and I'll have it sooner, but the 7 may be more worthwhile. (I'm not a particularly patient person.) I think I'll wait until rumors start coming out about the 7 after the 6s has been released, and decide then. Any advice anyone?
