iPhone Ring Tone Maker Application
www.iphoneringtonemaker.com
It's pretty neat and easy to use...even if you can do it for free. I tried it since you get 3 free ringtones with the trial. I was really hestitant on doing the other method with jailbreak, but this was real easy. I'm sure its probably using the same method but this one app does everything for you. Just thougth you guys might be interested.
Ok so its really simple to use. you just install the software, browse your music folder..pick the song you want as your ring tone and click create ring tone. next you just click send to iphone.(your iphone has to be docked) You then restart your iphone..go into settings/sounds and boom! its there. you can also use your mp3 ringtones as alarms. They give you 3 free ring tones and then the program is like 9 bucks to buy. Really guys. try it out!
