Thanks for stopping by the Apple Support Communities. If I understand your post, you've forgotten the passcode on your iPhone, and need to restore the device but don't have a computer. I'm happy to give you some information!
If you personally do not have access to a computer with iTunes, I can recommend borrowing one from a friend or family member (this will not affect their iTunes library), or you may be able to stop into an Apple Store or Apple Authorized Service Provider for assistance as well.
