Hi all, hoping someone might know hoe to help me, i have the Sony Ericcson Xperia X10 - new phone to me. I downloaded a ring/message tone (super Mario Bros) which worked fine, however when i tried to change my notification (msg tone) to something else it would just continue to play the Mario bros tune. I then deleted the download in hope that this would fix the problem but now the phone has no msg tone at all... it just vibrates. I have tried selecting other notification toned etc and turning the phone off and on but nothing seems to be working. Any ideas????
