Hi epage,
I recently encountered a problem and it seems it was caused by DIal Central.
It started when I realized I used all my date plan (500Mb) within less than a day and doing nothing special on my phone but sending a few emails and IMs.
I found out that my phone was sending a lot of data by itself and, using Wireshark and xterminal, found out it was communicating constantly with a google IP and that it was initiated by an app using some python component.

Dial central using a python component (python alarm I think), I decided to uninstall it, even though it was not running (just an icon on the desktop) and all data exchange stopped -- finally!.

I am not sure what is wrong, I had DC for a long time on my phone. I just updated Maemo before when it happened.

Just wanted to let you know, I'd like to understand what happened.
