I don't want to be mean, but coming to the forum and telling folks to dial a number, visit a website, or buy a product without any preamble or history as a valid contributing member of the community here pretty much means you're a spammer.
Aww, see, and here I came to this thread to actually talk about my ring tone!
I have the greatest ring tone ever. It's especially for fuddy duddies. It sounds exactly like an old corded telephone, before everything became beeps and blips. I love it. It's loud, high-pitched enough that I can hear it even in noisy conditions, and I never ever mistake someone else's ring tone for mine.
So. Back to the original question and ignoring the spammers: What's YOUR ring tone?
