Sorry yes, foregot to mention I also upgraded to the new Map - no idea what it gave me as u don't get release notes on these deltas.

The problem seems to be some obscure DUN issue between Map, Maemo's DUN support across Bluetooth and some phone networks. Some people have said they have intermittent problems - which almost sounds like some time related issues. Who knows. Wayfinder don't and don't seem to care that they don't.
