with DUN you can use your mobile phone to dialup to the Internet. It
makes you phone look like a modem. The audio profiles allow you to
connect a headset to your phone.

The WBTEXT service is some LG specific one and I actually like to know
what you can do with it, but this might be used by LG phones and
software only. However you might try "sdptool records --raw <bdaddr>"
and see if you find some more records.
