Can I use my own ringtones on the iPhone?

You can now!

Short answer is "no, not yet".

Hackers have indeed cracked much of the iPhone environment, so if you're up for that (and willing to take a number of technical risks plus patience to repeat the sequence for every iTunes push etc), then yes, it can be done. Details are available online, and several IRCs and Wikis have popped up to flesh out details. But this is not for the feint-hearted or non-techie.

Apple is expected to add this as a commercial service to iTunes. For example, savvy observers have spotted a "ringtones" tab in Apple presentations (see for example http://www.engadget.com/media/2007/01...), plus there is indeed a ringtones icon in the current iTunes distribution. The exact reason for why this was not rolled out together with the iPhone is not publicly known, but the obvious speculation is that it was among all the features that were rolled back for the initial release in the general QA panic. Personally I think it might have been a right-of-use issue relating to the current contractual structures around the iTunes store, especially since a big chunk of that library is under renegotiation with some of the labels.

The rumor is that the way it will work is that for a $0.99 fee you can convert any song that you have purchased on the iTunes store into a ringtone. In all likelyhood, AT&T will also do cross-promotions as part of their branding and overall marketing efforts.
