I am Martin Kalis from Sygic. We have recently published a new enhancement of contact list called .mobile Contacts. It is finger-frienly application with stunning user interface, predefined contact pictures from Digital Vision, contact groups, businesscard preview, text filtering, and some more unique features.
Since it's been published for only a few weeks, we didn't have a chance to test it with all Pocket PC devices - so please be patient with some incompatibilities and bugs. We would highly appreciate your help with removing bugs connected with your iPAQ hardware.
