It will have to come from the telco since your phone has limited storage. This immediately causes the service cost to jump some 10X since it's customized.
It may seem to you that you are not asking much but everytime you move away from any off the shelf device or what is offered be prepared to pay big time.
I limited my thoughts to just one item you listed. Add those others and such a thing does not exist in a handheld phone.
I own a small taxi co. It's not cost effective to have the dispatcher sitting at a desk answering a land line. Currently the land line is forwarded to a cheap cell phone. The cell phone mentioned, along with every other cell I've seen, does not have the ability to do what I feel, should be a simple and easy task. Todays cell phones are set-up so that when a tele phone # rings (that has been stored in contacts) the screen shows a picture or a 26-30 character indentification/name or both. I need a cell phone that can 1.Store unlimited contacts. 2. Show that contact info in paragraphs as the phone rings. (without pushing a bunch of buttons to get to memo) Example: Phone rings / screen says = Joe Blow #### Elm street, Nomally gets picked-up at X, nomally goes to Y, Cost is Z, His friend puked in the cab last saterday, etc. P.S. I've talked to motorola, blackberry and palms with no luck. With PDA's and Smart Phones you'd think this would be a piece of cake???
