Thanks DB.
I am not looking at iPhone at the moment, but all being well I will do. I take on far too many things at the moment. 18hr days seem to be the norm right now!
As far as requirements and mockups go, they only work inside my head....which is probably why I ended up working for myself

. I can make complex things work, but I can't explain why much of the time. Seriously though the first couple of apps will be basic apps (though still good quality), just to test the water and get learning before I get into anything bigger.
I want to get the apps connected to FB though, so I would like to pick your brains about that sometime if possible? You know the thing, "Shirley has just used Graham's stupid app to do x, why not join her".
