This is terrible, short-sighted thinking (the same that may be hurting the iPhone 4S' sales).
The new iPhone (iPhone 6) will have a bunch of changes over the iPhone 4S. Here are just some of the rumors:
- LTE chip
- NFC chip
- Double the RAM
- faster CPU and GPU
- "less shattery" metal back
- new & improved dock connector
- new stuff in iOS 6 that other devices won't get
The iPhone 4S had a crap load of changes over the iPhone 4 that people never seemed to notice:
- double the memory bandwidth
- new Dual core CPU with over twice the processing power
- much better camera optics
- 8MP camera
- 1080p video
- 64GB option
- improved antenna design (dynamic switching, no "grip of death")
Just going by all that, you know the new iPhone will have some beefed up stuff. Way faster CPU, maybe doubled memory bandwidth again. Maybe optical zoom on the camera. Maybe a battery with "16 hours" of use (up from the 7-8 hours people get now). Maybe a super-fast charge time (0% to 100% in 15 minutes).
We won't know what all the new stuff is until Apple shows it off. So again, seeing ONE possible screen resolution change in a hacked program and then going "AW MAN, THAT'S IT?" is quite silly.
