While perusing this thread, I was reminded about how much it annoys me that all V/Mail commands are different (i.e. press 1 for this, 2 for that, 3 to delete etc)
My personal phone is ingrained in my soul. I automagically press the right combo for what I want - usually to delete the v/mail message after I have listened to it.
My work phone from another carrier is different and I now have 112 saved messages. grrrr
