Im coming from a Blackberry device and the Iphone has been a great phone so far. However i really miss the blackberry ringer profiles.

A app that would provide settings for your ringers but be completely software based and is not affected by the position of the vibrate switch ( that thing gets put on acidently tooo often)

I would love a profile that rings my phone but keeps everything else quiet for when i sleep but still need to anser my phone in case of emergency.

also 3 dings per txt/email and other customisablibily would be nice.
