How to buy ringtones for the Sidekick (all versions):

1. From the Jump screen, scroll to Download Catalog and press the trackball
2. Wait for the Catalog to load (it can take a moment) and then use the trackball to pick a category. Categories are organized like the Jump screen ring
3. Select a category, and then browse the subcategories by folder
4. Press the trackball to pick a folder, and then check out the items in that folder
5. Once you find a ringtone you're interested in, press the trackball
6. The item details screen pops up and shows the ringtone and the cost. Push Preview to listen to a sample of the ringtone you're about to buy, and push Purchase when you're ready to download it
7. Relax and wait for it to download (speed will depend on your signal strength)

Important: There is a limit to the number of ringtones you can have at once on some Sidekick models! After about 10, be careful--you may be prompted to delete a ringtone.
