I was rifling around BlackBerry App World on my 9700 and discovered a pretty cool free application called DataBackup by S4BB. It backs up basic data (Calendar, Contacts, Memo Pad, Tasks, Call Log, Emails, Categories) from your BB to its microSD. It's fast and clean.
For me sometimes it's a pain to hook up my device to the computer and use the Desktop software to do backups, so this free app is pretty handy. Also, I can do a data backup when I'm not around the computer, too. Pretty handy.
It's free, not a trial.
Only thing is it doesn't backup settings and theme settings etc., just basic data.
