Just as a note...you CAN use your music as a ringtone, but you have to cut it down to 29 seconds or less. I don't know why AT&T puts this limit on the phone, as "unlocked" Z9's (and RAZR2 V9's) don't have this limit. It IS possible to edit this and turn off the limit, though, but you have to know a little about modding your phone (google it, you'll find out which sites tell you how...I've done it).
It's not that they are 29 secs, at's that they are over 300k in sizes, AT&T restricts that on phones now. I had several that were 40+ secs but under 300k before I hacked mine. But now I have removed the restriction I can choose any song of any length or size and apply as a ringtone, which it I know its only gonna play roughly the first 30secs, but when they are encoded at faster bitrate they sound so much better.
