It isn't serial, it's USB, but the concept is the same of course.

I think that you only need the /dev/ttyUBx if you want to open a
"pseudo-serial" connection over BT -- you would do that, for instance,
using minicom and connecting over BT to your phone to use it as a modem.
I'm not sure though, because I didn't try that yet. The only serial
connection I tried to the P900 was through plain USB to its cradle. This
worked straight away.
The rfcomm utility will open the /dev/rfcommx device, not /dev/ttyUBx.
The first 1 in the command specifies the rfcomm device to use, the last
1 specifies the channel to open with the P900. On my phone, channel 1 is
the "Bluetooth Serial Port".
Before trying the rfcomm command, did you succeed in the previous steps
? Are the BT modules loaded, did you try the hcitool ? The sdptool ?
