You have 5A rights at the border but I can tell you from firsthand experience after exercising them, I now get tossed in a cell every time I cross including spending 16+ hours in detention. IMO it's best not to have a phone at the border, I don't take anything across the border I don't want destroyed and documented and examined to the Nth degree. If you're not a citizen or green card holder they'll also send you packing for invoking the few constitutional rights you have at the border. Oddly they have always been incredibly scrupulous in returning money as long as its under the 10k limit, thoroughly counting it in front of me and placing it in chain of custody.
