I would never hand over my phone or passwords at the border. The only reason customs can search you at the border is for any smuggling or immigration issue. Since no rational person would smuggle something digital on their phone, when they could transfer it over the cloud without physical possession, there is simply no reason for them to search your phone without a warrant. If they threaten to take your phone, threaten to sue them for trespass and to go to the media.
