Will apple/google implement a mode to protect from unreasonable search by border agents? I personally would love a mode that:

- automatically wipes phone prior to powering off - wipes phone after X minutes elapsed unless the request is cancelled prior to the timer expiring.

The idea behind the feature is that you turn it on before going through a border crossing -- if you aren't submitted to an unreasonable search, then you can cancel the wipe request after crossing the border. If you are detained, your phone will wipe before it can be hacked or before you can be pressured to provide access.
