There aren't that many OS 7 themes out there for us to enjoy right now so if you're looking to spice up your device a bit then maybe these new 7 themes will do the trick. BB-Freaks has released 7 classically clean and simple themes for OS 7 devices in 7 different vibrant colors. The best part of these themes is that they're free! I will be downloading the red one, of course, as not only is it my favorite color but it's also the one that looks the best. Which one is your favorite colored theme?
