My guess is the difference is speed/latency.

I'm curious how my current version would work out. Its available in extras-devel, or you can grab the package directly at
http://repository.maemo.org/extras-d....9.1-0_all.deb

Besides some bug fixes, generalizing of CSV contacts (supports Google Contacts export and GrandCentral export), hopefully startup time improvements, and present but disabled GoogleVoice support (there is a hack for to enable it), this has a lot more debugging output.
