> I give them the password to unlock it (otherwise they would seize the phone) IIRC, I've read they can only hold your phone for 30 days or something like that, then they have to return it to you. They can delay an American citizen, but they can't deny entry. Ever since then, I travel with a travel phone, make sure my photos are backed up when I cross a border, and shut it down before I go through border control. If they demand a password, I'll put up a little fuss and then let them take it.
