My phone has been also searched. The kindly asked me to hand over my unlocked phone after they asked me to show that I have booked accommodation which I did on a phone. They asked who are these people on emails, then handed the phone back. They only quickly browsed through my emails though. My recommendation is that everyone prints on the evidence of the purpose of their trips beforehand: booked hotels and a list of conference they plan to attend (plans may change, however).
