I have the same setup. Recently I combined my OF database to include work and home items.

I have two context groups:
home
-computer
-errands
-calls

work
-computer
-errands
-calls

This allows me to focus on work at work and home at home and have all of it on my iPhone.

There is a slight problem with only seeing items in the iPhone for work that need to be done today. I solve this in two ways:
• flag items to get done today - these items I only flag from work projects
• due dates - this is what I'm using now. Creating projects that are due and using the due date flags on the iPhone to determine what I work with.
