What is CWM? For taking Nandroid Backups, flashing zip files, if you are caught in bootloops due to something wrong flashed WITHOUT backup of your important data, you can go for backup in TAR format from CWM Recovery and later on, extract the tar data and put in Titanium Backup to get it back... (YOU CANT USE WHOLE BACKUP THAT HAVE BEEN TAKEN AFTER BOOTLOOPS)  and for many more things :P you can search on google to know more about CWM ;)
