How do I trust a computer that was distrusted?

Community Answer

Try disconnecting and reconnecting the device to get the notification again, then click 'Trust'. If that doesn't work, disconnect the device and go to iTunes > Preferences > Advanced, and click 'Reset Warnings'. Confirm that you want to. Reconnect the device and the notification should appear again.
