Surprisingly, it's not better for business because of its faster performance, ultra-high resolution screen, folders, improved call quality or even multitasking. Its superiority comes from features and functions that have been under-reported and under-appreciated.
Here's why Apple's iPhone 4 is the best business phone ever put on the market:
The source of this quality comes from improvements to noise-cancellation software, a second mic for noise cancellation and improved microphone and speaker electronics. Most interestingly, the iPhone 4 boasts a very well designed "audio chamber," which improves the audio quality of speakerphone calls.
On the iPhone 4, the other caller will sound much better to you during speakerphone calls, and you'll sound better to them.
The Notes app syncs and assigns the label "Notes" to every item. Future searches for "Notes" brings up all of them. You can also sync different notes to different e-mail accounts, so you can keep business and personal notes separate.
The combination of Bluetooth keyboard support and Notes backup or syncing on cloud-based e-mail means the iPhone 4 is newly optimized for taking notes in meetings and generally using in place of a netbook for some users.
Besides, if you're going to do videoconferencing for business, you'd be well advised to do such calls from your desktop or laptop -- or from dedicated conferencing solutions.
iPhone 4 gives business people something much more valuable: Connection to family.
People who travel on business need to maintain connections to spouse and kids. Phone calls are nice, but FaceTime video calls are ideal. By buying an iPhone 4 for yourself, and another one for your spouse, you can share business adventures with loved ones, and you won't miss everything back home.
Camera phones live in pockets or other lint-filled places, such as purses and briefcases. They inevitably collect a tiny layer of microscopic dust bunnies that are hard to see, but that can subtly reduce picture quality. Even if you clean the lens, you'll usually find a layer of this stuff around the edges because they can't be reached by whatever means you're using to clean the lens.
The iPhone 4 camera lens -- both of them, actually -- are sealed behind glass. By cleaning the glass, which is easy, you can always bring your camera lens back to its brand-new level of cleanliness.
That fact combined with iPhone 4's respectable 5-megapixel camera with 5x digital zoom, HD video capability and on-phone iMovie video editing means that for insurance agents, real estate agents and a wide range of professional who need to take pictures for whatever reason, the iPhone 4 is good enough to replace a dedicated digital camera.
