Sony Ericsson

Hello Scoopers... i only have a couple of questions.

1st. Is there any way to modify the emoticons, I use the notes to share it thru the bluetooth, but there's only 4 of them and are boring as hell.

2nd. It is possible that i can delete all protected files from the phone, such as videos images etc.

Any info or sugestion will be apreciated.

Thanks in Advance.
