Sync with more devices using NuevaSync or ActiveSync (via Z-Push)

Currently the list of supported phones leaves a bit to be desired. I wanted to suggest that you look at NeuvaSync a iPhone (via exchange) to gmail and plaxo contact and calendar sync tool. Have you approached NeuvaSync about syncing with Soocial? It looks like they've been having problems with plaxo lately and they might be more receptive at the moment. I've had my own share of problems with plaxo the least of which was the comcast buy out and was excited to find Soocial.

I'd rather try to maintain a star topology for my sync efforts than use NuevaSync to sync to google and Soocial to sync from there.

It seems like it might be easier to implement an exchange like solution than developing standalone apps for the iPhone, win mo, and blackberry. Take a look at Z-Push: http://z-push.sourceforge.net/soswp/

Another site that supports plaxo (cringe) but not Soocial is Skydeck (http://skydeck.com/)
