While doing some research for our review of the 2008 Audi TT on Audi's Web site, we came across a selection of free downloads for your cell phone, including wallpaper and some very dynamic ringtones. If you're looking to pimp your cell phone and you dig Audis, then you're really in luck. If you just want to add some flair to your cell phone, well, the ringtones are pretty good. You can download ringtones named Energy Sweep, Melt Groove, or Moving Fast. They're all fast electronica clips that would make for pretty unique cell phone ringtones.
