Have you ever wanted to make a backup of your data, but iTunes wasn't around? Then iBye is the application for all your data needs. iBye will backup your data and store that data on a FTP server of your choosing. iBye will restore this data from the backup on that FTP server as well.
If you don't have an FTP server, iBye can do a local backup and restore. Other features include the ability to remove all the data from a desired application or lock the data to prevent deletion.
iBye supports Notes, Mail, Calendar, Photos, Address Book, Safari, and the syslog. iBye's FTP connection supports EDGE, 3G, and WiFi.
You can download and install the application from the ModMyi Cydia Repository.
