I have personally not had the level of frustration with my iPhones that you have, but I've heard of others like you. They seem to be rare, but that doesn't help the afflicted at all. This is going to sound flippant, but it's not. The few times I have had a problem, I've resorted to having my 22 year old daughter take my phone to the Apple Store. My 5'8", wavy blonde haired, slender, very attractive 22 year old daughter, who has seemingly perfected the art of mentally controlling men, especially the nerds at the Apple Store, and convincing them of pretty much anything she wants, including replacing malfunctioning iPhones for free. So if you have one of those types of daughters, or know someone who does, I suggest giving it a shot. And yes, I am perversely proud of her. Horribly evil of me, I know, but I'm a horribly evil type of person in general.
