I'm coming from a Treo so I'm trying to figure out how most of you actually make calls with the iphone (one thing the Treo clearly has over the iphone is ease of use as far as diailng your contacts). Let's say you have a friend named John Smith who isn't "important" enough to be one of your favorites but you do call him on a somewhat frequent basis. Do you go straight to the contacts app and start typing his first or last name? Do you just scroll down to his name in the contacts app? Do you tap on the "s" along the right side of the contacts screen? Or do you guys just go to the phone app and then go to the contacts app from there? Basically, what seems to be the quickest and easiest way to dial contacts whose number you don't have memorized?
