I use the shaguare phone from Austin powers as my ring, fuckinghorrible for my alarm in the morning (so named by my wife who discovered it on some obscure website), tngerror for a dropped phonecall, AOLgotmail for email, gotspam for sms, and other stuff for whatever. FYI, search the registry for .mid to change standard WM sounds to whatever you want (do this at your own risk, btw)
GET WINRAR HERE
.rar files are like zip files. It compresses them into a smaller size so it's easier to post/download them off the net. If you install winrar and then open the .rar file the sound file will be inside. Just choose "Extract" and point to where you want to save the sound file.
