To be sure, the 3G iPhone announced during yesterday's WWDC keynote is a big improvement over the original. But there are still a few detractors to keep certain people away. Here are five reasons explaining why you may want to avoid the 3G iPhone.5. The Camera. Apple made no improvements to the camera at all, and not even to the camera's software. Many of the world's top converged devices have cameras that range between 3 and 5 megapixels. The iPhone's 2-megapixel shooter is really a bare bones camera for such an advanced device. There's also no flash and no vanity mirror. On top of that, the software controlling the iPhone's camera includes no ability to make any adjustments to the shooting process or the camera's settings. You can't dial down the resolution, the quality, adjust white balance, or perform any other changes that even "free" phones can make. That's just poor. Perhaps Apple is relying on third-party app developers to create better camera software. Personally, I'd rather have Apple-developed camera software, and Apple didn't deliver.
