I have a question about my new iPhone....I came from the dark side and was a prior BlackBerry user. One thing that I did like was that BlackBerry offered different ringer "profiles", i.e. when I plugged in my charger it switched automatically to a custom profile that would shut off ALL sounds except for my phone ringer. I know I can do this on my iPhone manually but is there an app or any other way to do this on the iPhone?? Thanks
