What the hell’s the deal with ringtones? My phone (SE k700i) lets me just choose any song as a ringtone. Why does the iPhone require you to pay another $0.99 in addition to the purchase price to use it as a ringtone?

I’m clearly missing some enhanced functionality here. I mean, I just thought a ringtone was a noise (ie sound file) triggered by receiving a call…?

This is, of course, in response to the announcement that new iTunes lets you pay to make a ringtone out of a song you’ve already had to pay for.
