I believe that is a one year warranty if purchased from anybody, but if the reseller is not an authorized dealer then the warranty started the day the iPhone was purchased from an authorized dealer. So if I go into an Apple store today and buy an iPhone, the warranty starts today. If I then sell the iPhone to another person a month from now, the warranty is still in effect, it just says it started the day I bought it, not the day I sold it.
