The Apple Iphone: One of the worst electronics?

Whe it first came out it was the hottest new "toy" that everyone wanted- It held music, took pictures, Web access and many other unique features. Iphones sales shot up, but now I've heard alot of complaints such as calling disfunctions like not being able to answer, battery that doesnt last long at all and dropped calls. These are obviously not good for sales, so whats Apple gonna do?
