[Windows Mobile] mwalt2:
I only have a Rhodium, but I wouldn't think it would be device dependent. I can add a contact by going to 'all people', menu, new contact, choose contacts or sim, and then fill in the info. The contact is then added displays fine in the 'all people' tab. Where are you having trouble?

I am using the latest Leo version because it's the latest one that supports facebook without needing to modify anything (other then registry entries in core 2.5.2021).

I've attached my MASD so you can see what versions of things I am using.
