I agree that all of the sub-versions of the iPhone are slightly confusing, but at least they generally follow a pattern. There's always a clear progression, a higher number is always better than a lower number, and adding an S is an incremental upgrade over the non-S version. The Plus is always a larger size than normal. The G series and C series have complicated things, but generally speaking you just have to pick a number and then pick one of ~3 options at that level.
