I had an iPhone go bad last year for no reason, even the folk at the Apple Store couldn't figure out what was wrong with it besides "it doesn't work". It was fine, then one day the battery started to drain quickly and died and it wouldn't charge again, it was only 14 months old. I have the Wells Fargo card that offers cell phone protection, but it wasn't covered since this was due to "normal wear and tear" which is ridiculous for a $600+ device after 14 months. However, I had purchased the phone with a different Visa card that doubled the warranty. They did not pay me for the full value of the phone, but did cut me a check for what I had originally paid for the phone which was $180 (I had signed a contract at the time, that's why the price was so low, it was subsidized). Apple charged me $300 for a used phone of the same model. So in the end I was only out $120.
