Install SPB backup to your SD card. Then you can play around to your hearts desire and not have to worry about __cking anything up. You can just do a full restore from backup on the SD card if you hose something. That's how I learned.

Get the backup software and learn how to use that before you do too much to your phone. That way you won't have to worry about all your work going down the drain with one wrong mod.
