Yes.  DUN showed up, but I don't think he has tethered data setup on his
account with Alltel so it wouldn't connect, either.

On my MotoROKR Z6m, I have DUN, OPP, FTP all setup to automatically give
the N800 tablet access to the various services, which it does very
nicely, but ONLY ONE AT A TIME.  It is incapable, for instance, of
transferring a music file from the internal card on the phone to the
tablet's File Manager app over FTP while the phone is DUN tethered using
the phone as a modem.  You must disconnect the DUN tether, first, then
the file manager has no trouble getting to any file stored anywhere on
the phone, even the system files.  This is also true of headphones,
handsfree or A2DP.  If the phone is connected to any headphone, you
cannot connect to it with any other BT device.  I'm amazed it can handle
handsfree simultaneously with A2DP to my Motorola S9 stereo BT headset.  
The phone is really dumb.

It's a BREW phone.  It defaults to the manual access you're seeing but I
can go into BT then DEVICES and pick the tablet and EDIT to light up
automatic access for this device.  From then on, DUN connects via BT on
its own, even before the tablet boots past the bootup splash screen with
two hands on it.  By the time the tablet boots the GUI home screen,
[Alltel Connected] pops up instantly...already logged on and checking for
updates to installed software/setting the clock from NIST's server/etc.

Thanks for this information, you've been a lot of help.  We'll play with
the Q, again, to see how well it works.

One more question on your WMx phone..... Can you use the internet on the
WMx phone while BT DUN is tethered to an external computer, or does it
only support the one connection, either the phone or the DUN device but
not both?

The phones need to be like the Nokia N8xx Linux tablets.  The tablet will
simultaneously connect to DUN on the phone, the S9 handsfree, my Nokia BT
folding keyboard and Nokia BT GPS receiver...with no conflicts as long as
you keep the various BT devices separated from each other by about 5" to
keep this one's transmitter from SWAMPING that one's BT receiver, causing
packet crashes in the busy local BT band its all swarming in.  

To simplify BT stereo to the S9, instead of multiple pairing and
unpairing it, a total nuisance you must do to prevent more than one BT
device from trying to connect to it at a time, I use a Sony TMR-BT10
Stereo BT transmitter (rechargeable-tiny) for all my stereo gadgets, bt
or not.  I simply plug the Sony's miniplug into whatever stereo source I
want to hear in the S9.  It works fantastic!  The S9 A2DP is ONLY paired
with the little Sony transmitter so repairing is unnecessary.  I have
many old MP3 players (Xclef 500 w/120GB drive, Archos Studio 20) and the
Sony lets me use them with the S9, too.  S9 is a fantastic stereo
headset, NO MECHANICAL NOISES something that really pisses me off on some
really expensive headsets.

Again, thanks for your help....(c;
