OUIs are the first 24 bits of a MAC address (Bluetooth or Ethernet).
With this app you can see which company owns a MAC (e.g. 00:09:2D for HTC), or vice versa.
The database is locally stored on the SD and can be updated online.
To do a wildcard search, use the '%' character.
Please email me with any bugs/problems/feature requests. I cannot reply to market comments which can make debugging difficult.
