If you don't grow where you're planted, you'll never BLOOM - Will Rogers
I can't speak for her, but I used to drop calls frequently (it's gotten much better in the last year). Now I occasionally have full bars but no signal, if I'm someplace that has too many iphone users (for example, I was trying to get driving directions after leaving a Rockies game last year. We were in an area that usually has fantastic service, but the towers were flooded with people trying to do the same thing, so the map just never loaded).
My iphone has been invaluable for my work though. I realize that there are other phones on the market now that do the same things, but I see no reason to change!

Either there's no 3G signal at all (off the beaten path), or the network is so congested that they have to wait for literally minutes to, say, load navigation, Urbanspoon, or whatever, on a purported 3G connection.
I only know one person with an iPhone 4, but he says the antenna issues are just as bad as reported, and the rubber baby buggy bumper doesn't entirely solve it.

Interestingly, I have the iPhone4 and have never had the antennae issue...
