You hear this a lot, the iPhone can't do the one thing it's meant to...be a phone.
Well, no, the iPhone, despite it's name, is by design and intention, less of a phone than a computer and media device. If what you really need is a phone, with some minor web capabilities, a Razr with that ridiculous medianet crap should suffice. But the truth is we don't by the iPhone because we want a phone, most of what we want from it has little to do with the phone part.
So, sure, if you have reception issues, which neither I nor my wife do, it's aggravating for sure, but the often said idea that first and foremost it's a phone, isn't really accurate and just hyperbole. Yes it has a phone component, and it should of course work, but the idea that the iPhone's main purpose is to make calls is just BS.
