Ring tone from Sprint

[ccoll5]

hey guys, im new to the ppc, ive got a mogul. i got it 2 days ago and have been playing with it non stop, im switching over from a palm treo so its just a "little" different. i was wondering if you could download the ring tones from sprint to the phone. i have $20 in premium service credits with my plan and i have tried downloading some ringers from sprint and it wont work. could you guys let me know if it works or if you just have to make your own and transfer to the phone from the computer. thanks guys ahead of time and sorry if this is a noob question.
