Chef, I totally respect your decision above, but as someone who just upped from a 4 at no small personal expense, god is it ever a true night and day difference.
If you use your phone as often as I do - 2-3 hours a day - the performance improvements, increased speed, LTE, larger screen, incredible camera - it's all so worth it. The device is a pure pleasure, a real wonder.
All that said, yeah, I don't take anything for granted and the 4 was still doing me right to this day. I'm still marvelling at smart phones in general, almost as much as I did back in 2009. Truly amazing products that fit in our pocket. Models from back then can still get the job done.
Kudos to whoever that Gaffer was that made the thread about trading in his iPhone at Gamestop. I upgraded from a 4S to 5S and was looking into getting the most value with little risk for my 4S. With the current additional 30% promo, GS gave me $350 for my 32GB 4S. That's more than any other place including eBay seems to be paying for them. I also followed another Gaffer tip and put it all towards Amazon gift cards.
You're welcome!
(I think it was me; I've certainly talked up trading in iOS devices a bunch, haha)
When I got my 4, I got rid of my 3GS the first week trade-ins were available at Gamestop in Canada; they hadn't figured out their pricing at the time, so I got $230 in credit there for my 16gb. You get tax too, so, if you bought something for $250, you'd only pay tax on the $20 difference. It's great here (where sales tax is 13%).
Sadly they've smartened up a bit and offer less now. My 16gb 4 only yielded $120 ($135 with tax), but that's still a nice chunk off my forthcoming PS4 purchase!
