some are on the "S" cycle, iphone 3GS, 4S, 5S(eventually) and of course others are on the alternate, iphone 3g, iphone 4, 5, etc. I always have this impression that the "S" cycle must be better since (other than some spec updates its essentially the same phone they are working with, but the build and internals are more refined and maybe more well thought out/efficient/reliable. I imagine a lot of the changes being left overs from a checklist that never made the release date of the previous "new" model. Can anyone attest to the 'S' models being any more solid of a user experience or reliable? Obviously the newer the phone, the faster its going to be. But in general, for what the phone was expected to do at the time, do any models stand out at as having been a more satisfying or less satisfying experience?
