I wish following features existed in Bada OS:
* If I have SMS messages in a folder, I have to be able to move them to inbox and/or make a backup of them.
* I could delete all "Delivered" messages at once.
* I could sync my calendar with google calendar.
* Phone alarm runs when the phone is turned off.
* Sometimes phone doesn't vibrate when I'm being called or sent SMS but it' lit up.
* Sometimes alarm clock doesn't work.
