Pros Faster internet, much faster the the older models. combined inbox, the face time works just like they say. I only used it once but it worked really well.
Cons unable to set a different sound for each inbox. software seems very glitchie. My bluetooth no longer works correctly (tried 3 different ones). Overall i'm not impressed and am thinking about going back to the blackberry
Summary I'm a sotfware project manager and use a blackberry. I rely heavly on email and my syncing with Outlook. I was was hoping the iphone would make the jump for business uses. So I sold my blackberry because in general i'm an Apple person, my personal computer are Apple and had high hopes for the iphone 4. However, all in all it falls short. It's a great toy and it has a great Apps but it just not ready for business primetime.
Pros Internet browsing on this phone is a LOT faster than on previous models. I could not be happier with the speed--it blows all other mobile phones away. The apps are fabulous too. Screen is gorgeous. Touch screen is easy to use.
Cons Two words: PROXIMITY SENSOR!! The sensor is broken. It doesn't detect your cheek and the screen activates, calling other people while you are on the line. I can't tell you how many times I've had to apologize to people because of this.
Summary Proximity sensor issues make this phone all but unusable. It's more like a mini iPad.
Pros Everything you like about iphones: apps, web, beauty, design.
Cons It doesn't make calls, so it's not a phone
Summary This phone dropped every single call I made, hence it is not a cell phone, it is a toy.
Pros The convenience of using it. Just like all the other iPhones
Cons Bad reception. In 3 days that I had it, there were numerous dropped calls, failed calls, searching for service. But I think something was not right with carrier.
Summary I had to return it because I missed important calls, but only after I called AT&T customer service. The representative said that he doesn't know why such bad reception, according to his map I live in a very good reception area. Then I went to AT&T store. They replaced the SIM card. I still wonder how that helps. Then I went to Apple store. They replaced the phone. After that I came home, made one call to the iPhone to check the reception. The call failed.
The next day I went back to AT&T and re-activated my old 3GS. Still bad reception, but at least calls get through now.
The next day I returned iPhone 4 to Apple store. They couldn't, for some weird reason, put the refund money back on my credit card. I had to accept cash. And they lied on the "Work Authorization" application. Instead of saying that I was returning it because of problems with reception, they put on the Application "Issue: phone battery only lasts 20 minutes".
I signed it because I didn't care and just wanted to get rid of this phone. But it is a good question why they put the wrong reason for returning on that application.
I am getting disappointed with Apple.
Pros Fast, glitch free operation. No Windows Mobile like sluggishness. Outstanding screen. Accelerometer really works! Apps are magic! This smartphone functions intuitively. Why did I wait so long to buy an Iphone?
Cons Occaisional app hiccups, but this device is still light years ahead of any smart phone or mobile phone I have ever owned or tested.
Summary The antennae issue is so minor. Steve Jobs is correct, the issue is overblown. Buy a case and the problem is gone. You'll want one anyway to protect this jewel. My highest recommendation for the Iphone 4!
