Having troubleshooted this for some time attempting to do what I
imagined would be a reasonable feature of the phone, I figure I should
share my results with others who may be looking for the same
information.

My main objective with purchasing the DCU-11 was to be able to
synchronize my phone with Outlook, to avoid having to enter each one
of my contacts into the phone one at a time.  When you've got this
many, it isn't an option at all.  This is the story of my attempts.

I purchased the data cable and found that it only comes with the
drivers.  These installed correctly and I now had a virtual COM3 port
in device manager.  At this point, the installer directed me to the
Sony-Ericsson web site to download the rest.  This must be the new
"server yourself" approach to doing business.  [They offered
explanations that the CD was made before the software was available,
but that meant the CD that I just got was many month old.]  Going to
the site, I [eventually, the site leaves a lot to be desired] found
the MMS Home Studio and the Image Editor, neither of which were of
much interest to me.  I installed both of them anyway, one of which
installed the needed Phone Monitor Options shortcut in the Control
Panel which seems to act as a gateway for the software to communicate
with the phone.  Unfortunately, Phone Monitor Options does not see the
phone when connected, although it sees the USB cable as COM3.

Unable to go any further after hours of research, I [again,
eventually] found their tech support number and called them to ask
about these two problems.  Where is the Outlook synchronization
software and why isn't my phone recognized in Phone Monitor Options?

The tech support woman answered that the T226 has no ability to
synchronize with Outlook, and that the phone is not supposed to show
up on the Phone tab in Phone Monitor Options.  Only the USB cable is
supposed to show up in there.  According to her, that was enough for
the two [IMO useless] applications to communicate with the phone.

Whether this is the case or not I am not sure.  Regardless of my
certainty, I have not been able to make this phone do anything usefull
with the DCU-11 besides manipulate the themes and create multimedia
messages.  You cannot download new games or synchronize Outlook with
the phone.

My advice to any looking into this currently: don't bother buying the
DCU-11 data cable, unless you intend to get a better phone in the
future (and want to pay $30 for practically nothing now).  My advice
to anyone having these problems also: stop wasting your time, we have
been mislead by the sales description of the data cable.  My advice to
anyone looking into buying the T226: it is a cheap phone, and you'll
get what you pay for - a cheap phone. (And the menu system is slow as
snot, so don't be in a hurry.)  My advice for anyone that already has
the T226: get rid of it as soon as you can afford an upgrade, and
consider it a loss.

Any information that can lead me to the contrary of my finding would
be much appreciated.  Otherwise I waited for 2 months for
Sony-Ericsson to ship the data cable to me for nothing.
