Just as Lifeblog isn’t meant to work with two databases, it’s not meant to work with two phones. I’ve tried it. The items all transfer well to the PC, but then it gets hairy with the Favorites.
I think the model used to design the Favorites didn’t expect more than one phone or item database at a time dedicated to Lifeblog. Makes sense, since Lifeblog is not meant to do these things. 😉
But, it would be cool if a family, or say, and event could have a single Lifeblog to which all the items were transferred and each person had their own Favorites. I don’t know.
