not yet...but all ringtones will likely have to be purchased.
MP3 ringtones are obnoxious anyways. think about it. No matter what song you set it as, there's always a situation in which you really don't want that particular sound to play.
Like if you have too $hort and youre eating dinner with your gma.
Or if you have DJ mix a lot and youre in a meeting with your boss.
Or even if you have a love song and youre with the guys.
Plus they all get old after a couple weeks anyways.
someone has got to find a way to make them, I mean my sprint a900 was easy to make ringtones and send them over the internet and i only paid like 99 for that phone, I spend 500 on this one and I want to make ringtones dammit!
For any mp3 ringtones, you will most likely have to buy them. i personally don't think they will be allowing any software that lets you make your own. At least judging by the evidence ive seen so far.
