For all of you who have problems connecting to your mobile with PhoCo, there is a testing app available called "PhoneTest". It's originally shipped with the PhoCo Setup and resides in the application directory after installation.
I've beefed this app up a bit for release of 1.4 and now it gives you detailed hints on which port to connect (if possible). This especially is supposed to help people with Motorola or Symbain OS phones.
You can find it here for download: http://phoco.net/PhoneTest.zip (http://zoran-horvat.de/private/CarPC/PhoneTest.zip)
Before you can run it, you have to extract it into the PhoCo installation directory (because of the .NET runtime).
Skinning to go... VisualDesigner2!
