Finally, I have something other than my obvious wit and charm to offer you all! I recently upgraded from my iPhone 3gs to the new 5, and I am sooo in love that I wanted to make myself some wallpapers. I plan on making more as inspiration (and skill) strikes. These are totally free for you if you want them! I even tested them on my smaller 3gs screen and they look just fine.
Feel free to share these if you want to on your own blog. Link me back and I'll be a happy camper.
