My wife recently got a Bold 9000 through warranty exchange and I cannot for the life of me figure out how to change here text notifications.  So I was just wondering if anybody knew of a way to change the sound the phone makes when receiving a text message.

Seems like a dumb enough question but for some reason I just can't figure it out haha.

On another note, if I wanted to upgrade her phone to OS 5.0 would I have to unlock it somehow first or is it just a matter of installing it (seeing as how AT&T is taking forever for the release)?

Thanks in advance.
