Since the kids got new phones, they've been busy learning all the neat things they can do with them. Now that they aren't limited to the ringtones that come with the phone, I know they'll be looking for some free ringtones to use, and I was reminded of this site I signed up for back when I first got my phone - phonezoo.
Phonezoo has free ringtones for your phone. You can register your phone and have them sent to your phone, or do like I do and download them to your computer and then put them on your phone. Now that I know how to transfer files between my phone and my computer that works really well! Also, with a phonezoo account, you can save ringtones you like to 'my zoo' and easily find them later - so you don't have to download them all at once.
Phonezoo also lets you create your own ringtones from sound files on your computer and share them with the rest of the phonezoo community. I haven't tried that yet, but it could be fun...
Here's a ringtone that would be especially perfect for one of my friends:
