What Kre also fails to acknowledge in his theory that you're best sticking to the "odd" update cycle, is that you get the device on the second release of the same design. So while you sit there with your 4S and smugly praise it right now, when the new design comes out and you (as I presume from your posts) keep your 4S for another year, you'll have an old design AND an inferior device technically.
Sure, you'll get the NEXT iPhone, and begin your theory again, but your own way of doing things is nothing but a mirror image of how I do things. I buy a new device on the first redesign, miss out the following device with the same design used, but upgrade for a significant technical boost AND a new design.
You buy a new iPhone on the second design iteration, enjoy the device being technically relevant for a further year, but have to see a completely (inside and out) iPhone on the market for another 12 months before you upgrade again.
Horses for courses. No one is wrong, and you should stop telling some people they are.

Quite! It works really well on the 3G.
It makes me wonder if Apple agreed to withold turn-by-turn from older phones as part of their gps technology deal with TomTom? I can easily see TomTom making that stipulation, since it would let them wring another year or two of revenue from their stand-alone app. TomTom must be hurting right now: High-margin standalone GPS is dead, and iOS 6, had it supported turn-by-turn on older devices, would have killed another revenue stream. At least this way, TomTom have bought themselves time to rejig their business model.
It might even boost TomTom's revenue if it encourages older device owners to buy the app to, "keep up".
You know, this theory may not be as far fetched as some reading it may think.
The new maps app clearly displays the TomTom logo, which could be something simple like basic acknowledgement or something more clever like subliminal marketing. An iPhone 4 owner using maps on iOS 6 sees the TomTom icon, but sees they don't have Turn By Turn navigation may, by that rationale, go to the App Store and have a look at the TomTom app. Personally, I'd think "£50 for something the 4S does for free"?!?
However, some may well buy it, and remember that while TomTom sells for £50 on the App Store, Apple take their usual 30% cut, which is a handsome £15 per copy sold. If even 1000 iPhone 4 users, and that is plausible, decide to buy the TomTom app, Apple nets a tidy £15,000 for simply omitting a feature that the device an handle and then some.
I could well be over thinking things here, but your point in bold raises some questions.
