I'm a New Zealand citizen and I might soon be visiting to the US on short notice for business. I've heard that the US have started to frequently search cellphones. I'm not very comfortable handing over my phone and lock code to US customs - as well as copying the contents of the phone (including passwords, giving them unlimited access to all of my accounts) if it's out of my sight they could install extra software or hardware.
But obviously, a cellphone is a must when traveling overseas. Would it be a reasonable idea to get a second, cheap cellphone just for this trip?
Or am I being excessively paranoid? I've never been to or through the US before, only heard the horror stories.
I'll also be bringing a company laptop, but I'm not too concerned about this since I've deliberately avoided storing personal data or credentials on it, and it's a US company.
