"Great gadget, unless you want to use it as a phone"3.0 starson by vmvmvm44
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.
