Soundhound - If you're listening to the radio and you aren't sure what a song is, it'll identify it.
Pandora is really smooth operating too.

Tips:
From the "lock screen" double tap home button to bring up the camera. Slid the camera button up.

You can access Siri from the lock screen by holding home.

While listening to Music, at the lock screen, double tapping home will bring up Music Controls.

While in Camera, pressing + will take a picture when you have the phone horizontal.

Double tapping home while the phone is unlocked will bring up your latest apps.

Tell Siri who you're related to. Bring up Siri and say blank blank is my Wife. She'll have you approve it, that way you can tell her to text or call your Wife, and she'll know what person to call. You can also do it with Work, Home, etc.

That's all the tips I can think of, completely out of order.

Do you have a Case?
