Is there a "conference call" app out there? One that will dial the number for the call and enter the pin at the right time?
I seem to spend time scribbling PIN numbers down it switching back and forth between mail/calendar and phone entering 9 digit PINs in groups of 3.
I'm thinking something like tripit - you forward the invitation to the app (or better, it plucks it from your calendar) and it cues up dialling and PIN entry for whichever concall provider is in use without any hassle.
Too much to ask for?
