I have several sounds and rings I use for all sorts of stuff, and I switch among them pretty frequently. They’re all WAVs or MP3s, and my favorites are:
[ul][li]A mariachi trumpet intro – currently my new message tone[/li][li]The theme from The Price Is Right and that sound for when someone loses[/li][li]A regular phone ring[/li][li]Bananaphone[/li][li]Lindsey Naegle (the Corporate America woman from The Simpsons) saying “I’m a sexual predator” – that gets some stares[/li][li]The Futurama theme – this makes an awesome ringtone[/li][li]The Jetsons doorbell sound[/li][li]The computer from DS9 saying “There is one message waiting for you.”[/li][li]The TNG red alert sound[/li][li]“Tomorrow’s Child”, from Spaceship Earth[/ul][/li]I also have some merengue and Latino pop that I use as ringtones for specific people. I change them fairly often, as my phone can play damn near anything for a ringtone, and getting them on and off is extremely simple – yank the MMC card out, or via Bluetooth, or with the data cable.
And I swear on a stack, whenever I’m in public, it’s knocked down to a simple soft beep with vibrate or just vibrate. I’m not one of those people.
