Head to the Wifi tab and check the boxes that represent Wi-Fi networks you're connected to on a regular basis: home, work, relatives' and friends' homes, and so on. Don't check boxes for Wi-Fi spots at coffee shops, airports, or the like. Over in the Bluetooth tab, you can be more liberal, checking boxes for any headsets, laptops, cars, or devices to which you're often connected. BTWifiUnlocker only unlocks your phone for those specific Bluetooth devices, not any device with the same name. So no need to worry about a rogue agent with a FitBit gaining access to your Evernote stash.
That's really all I have to say about Bluetooth and Wifi Unlocker, other than to note that the free edition I'm linking limits you to one Wi-Fi and one Bluetooth device--which might be fine for some users. To get more devices added to your whitelist, you'll need to buy the $3 full version.
