Come ON! You guys should learn to think like Apple. Apple don't think in terms of 'specifications'... i.e. how many GHz a processor runs on and stuff like that, but in terms of capabilities AND aesthetics. My wishlist:
- a better phone connection. Apple will find a way to improve the the phone's ability to connect in poor signal areas, such as elevators for instance and reduce dropped calls way below industry standards.
- a longer batter life. The iPhone 4 is MUCH BETTER than the 3GS in batter life, but I foresee Apple shooting to improve further.
- even better pictures and videos. Apple don't think in terms of number of pictures but think about those features that make for better pictures and videos. It may be possible that we'd see more megapixels, but I won't bet on it. What I think we'd see is a better software, maybe an improved lens system, a better range of quality pictures in varying conditions (right now, the phone is stunning in bright light conditions, but can be chappy indoors). Possibly a few additional camera settings beyond tap-to-focus.
- a more social phone. I expect greater integration to social networking built directly into iOS 5.
- improved security. There are patents to suggest physical security features that will enable the picture of a phone thief taken will make an appearance soon enough. Better phone encryption and protection from web threats.
- an improved user interface. possibly an active status bar. New forms of text input. wireless syncing to iTunes. Greater personalisation of the look and feel.
- better gaming experience. better graphics.
- better integration to the 'macworld' of devices. It's common for people to have a mac pc, iPad and iPhone. I see Apple finding a way to leverage this to create a better experience for those with multiple devices.
- minor design changes: I don't see a major redesign until iPhone 6, but I foresee a minor change if any antenna redesign necessitates it. However, I'm confident Apple will stick to their guns and maintain the form of the phone, even if they change the material used in making the antenna in some way.
