I used Glyphboard for mine, which is a web-app for the iPhone that has a bunch of characters, one of which is the apple logo.
Visit this page on your iphone:

To install Glyphboard, tap the + button and choose Add to Home Screen. Once installed open the app and select the Glyph you want and hit copy...You can then paste it into your carrier and/or folder names (you can also use Emoji as carrier and folder names).

Thanks for you help, didn't realize I already had it installed a while ago.
