BTcached

Already paired devices have a key in a list.

Version 3.0:

• Database with bluetooth addresses is now in separate PDB file
• Now you're able  to update this database anytime from http://3division.net/hub/btbase/btcached.pdb

Version 2.1:

• Added more devices in a database
• New warning dialog when deleting unpaired devices
  

Version 2.0:

• Hi-res+ implementation with landscape too.
• Application is guessing the manufacturer of the device by it's BT address. It's just guessing so it's not sure (you can see T630 instead of K700i in screenshots)
• Now you can display BT addresses
• Fixed "Delete unpaired devices" bug

There is a "Delete unpaired devices" item in menu so you can quick clean devices which aren't in your trusted devices list.
And now you can easily show BT address.
