I had it on all the other phones I had, but I haven't seen one for the Storm yet. Anybody know of one that will let me edit my MP3s (cuttings sections and what not) and use them as ringtones?
Won't help you on a PC, but if you have a Mac, you can do it with GarageBand. It's how I make mine.
I used this guide for the iPhone to figure it out. The primary difference is that instead of send Ringtone to iTunes, you have to do send Song to iTunes, then sync it to your BB somehow (I use Missing Sync, so I have a Ringtones playlist that I have setup in MS to sync to my BB).
Obviously not helpful if you don't run a Mac, but in case a Mac user reads this too...
Edit: Just saw your last post, and obviously this won't help for on your Storm. To the best of my knowledge, there is no way to do it on your phone yet.
myxer.com is a great tool and supports editing mp3s that you upload or just use prior on the site. As well has wallpapers and games. for the storm though the games dont work yet.. and ITS all FREE.
I don't know of any that work on the phone itself either but as was stated above, audacity works great on pc also. you pick the length of the ringtone and the part of the mp3 you want to use. Just edit, upload to Storm and set as ringtone.
