I just upgraded my iPhone 3GS to iOS4.0.1 and JB it using jailbreakme.com.. I have 2 questions
1. I understand there are some changes in iOS4. How do I change the ATT Carrier png and the statusbar notifier icons??
2. How do I change the sound files (mail and SMS alerts)

I realize there aren't a lot of themes for iOS4. So I need a way to change these files through SSH. I used to paste them in to the System/Preferences/Core Services folder before but now that doesnt seem to work...

Please Help!!!
