Looks like the 5th amendment should apply to your iPhone: you have the right to remain silent to avoid incriminating statements. Since your iPhone contains a lot of information about you, where you were, what restaurants you like, what pictures you take or save, your contacts, your messages, etc., I would suggest that the 5th amendment should apply. It's more than your property safe from unreasonable search and seizure by the 4th amendment.
