right. but i wasn't asking about what Symbian phones need, i was asking 
if the above two steps are what has to take place in Bluez to end up 
with a Linux Bluez-driven box advertising a SPP-based service with 
specific UUID.

"man sdptool" returns nothing. the only thing i can look at is "sdptool 
--help". if that's not what you were referring to, where is sdptool's 
manpage?

%sdptool add --help
add [--channel] service
