might know, that I'm not too happy that Microsoft removed the Bluetooth dial-up
networking (DUN) functionality from Windows Mobile 5.0 and Windows Mobile 6 but
replaced it with Internet (Connection) Sharing instead. However, there is one
benefit - I have to admit - which makes Internet Sharing better: it works
seamlessly with GPRS counters like Spb's GPRS Monitor.
In the past with using the DUN functionality, a connection was established from
the Notebook. This means, the connection was created on the Notebook by dialing
*99# and configuring the APN on the Notebook as well. Then, the connection was
initiated from the Notebook and the Windows Mobile smartphone was just a dumb
modem which received all the commands from the Notebook.
This changed with Internet Sharing. Here, the connection is established from
the smartphone and after the Notebook is connected to the Windows Mobile device,
either by USB or Bluetooth. Since the Windows Mobile device is using the native
GPRS or UMTS connection which is configured on the device anyhow, GPRS counters
like SPB GPRS Monitor can measure the used bandwidth as well as it can show the
current connection speed - something which was impossible before with DUN-based
While I wouldn't go so far to say Internet Sharing and I are the best friends
now and I'm not missing DUN anymore (DUN had other advantages for me), it's a
handy feature to have real time statistics about speed and used bandwidth
available on the Windows Mobile device screen. Especially if you don't have a
flat data plan but if you have to keep an eye on your used volume; because now
everything is counted in one single location - your Windows Mobile smartphone
which can even calculated the costs for the connection for you - as long as you
use a data monitor like the above mentioned GPRS Monitor from Spb.
All we need now are some proper working GPRS and UMTS monitors for Windows
Mobile Standard smartphones as well - because most I've tested so far didn't
work proper with Windows Mobile 6.
