hi, i have a macbook intel duo. and i have never really modded before. i have a slvr L7 but it is not the phone i use with my SIM card. it is just sitting around. i really want to use it to listen to music and as an alarm clock still though. but when i start it up all its says is insert sim card and i cant do anything. what program do i need to get to mod it so it will run?

thanks
