On many other phones, when you purchase a ringtone, it "expires" after, say, three months. This is not to say you can't use it anymore, but if you got a new phone, or something to that nature, you wouldn't be able to move the ringtone over to your new phone. Do the iPhone ringtones bought in the iTunes store work the same way? I have a couple of ringtone ideas in my head, and plenty of money in my iTunes account since it's the holiday season. If I get an iPhone in March, and I bought a few ringtones now, just so I could make sure I don't run out of money by the time I get the iPhone and have to go out and buy a card just for that, would I still be able to use them when I did get my phone in March?
