What is the easiest way to change the new mail and new voicemail sounds? I've heard that you can use a file browser to locate caf files and rename. Don't want to jailbreak. Where can I get an iphone file browser for XP?

You have to jailbreak to be able to access any file on the iPhone.
Then use iphonebrowser or DiskAid to access.

Yep, gotta jailbreak

Then get ToneFXs
with thier program and app you can make the sounds transfer them to your phone, and change the sounds of your typing, sms, and others..

Quick simple and painless...
