The good news is that customs agents will now need to have "reasonable suspicion" to perform a thorough search on your phones. Usually, an advanced search on electronic devices in airports means connecting them to an external gizmo that can analyze or copy their contents. Border guards can still manually search your gadget without a warrant, though, since the updated directives now state that you're "obligated to present electronic devices and the information contained therein in a condition that allows inspection of the device and its contents." One possible interpretation for that is you're expected to unlock your phone if an agent asks. It's not clear if you have the choice not to comply, since officers can apparently "detain" a device if they can't complete an inspection.

While you can put your phone on airplane mode to prevent an agent from looking through emails, notes, documents and files saved in the cloud, that's definitely not enough for the ACLU. The organization, which filed a lawsuit against Homeland Security over this exact issue last year, said in a statement:

"It is positive that CBP's policy would at least require officers to have some level of suspicion before copying and using electronic methods to search a traveler's electronic device. However, this policy still falls far short of what the Constitution requires -- a search warrant based on probable cause. The policy would still enable officers at the border to manually sift through a traveler's photos, emails, documents, and other information stored on a device without individualized suspicion of any kind. Additionally, it fails to make clear that travelers should not be under any obligation to provide passcodes or other assistance to officers seeking to access their private information. Congress should continue to press CBP to improve its policy."

We've got a feeling that despite the new directive that calls for "reasonable suspicion," these updated rules won't be bringing the number of searches down in the future.
