That is my understanding - I don't have an iPhone to test it with, but I believe the same issue applies to some/all smartphones. And its not everytime you turn the phone on/off but every time you turn the gps feature on/off. If you have cell towers or wifi signal in range then you won't notice it (in fact it should be quicker than a normal gps in the same circumstances) but in the middle of nowhere it take a long time.
