MS is not stopping you from using TomTom, TomTom are stopping you until they make a compatible version.
Activesync will not happen and the same with cab files I expect, but technically you don't need cab files when the only compatible apps at the moment are on the Market Place.
I guess you are right, does seem silly being forced to use data allowance to sync calender etc, anything that works via usb data cable would be fine for me. Theirs no setup allowing ftp connection either, I'm sure i saw it on my Omnia 2.
Considering my solution is Google, surely MS should be thinking, don't like that solution must sort that out.
I have apps on my Omnia 2 that are useless now, I likes being able to plug it in and then drag and drop files of my choice to it. I know MS are clamping down but the whole reason I likes Windows Phones were ease of use and not being clamped down on. To me, MS are going the apple way as Zune is basically ITunes as far as I see.
BTW, Surely i'm not the only one with one of these phones, perhaps i'm just the first poster on the forum
