So, don't know if this has been posted yet...but it's kind of cool so I figured I would share the love. I had a 1st gen. iPhone which was jailbroken and had a custom carrier logo on it (my initials.) When I got my iPhone 3g, I restored using the previous backup from my jailbroken phone. Much to my delight, I saw that my custom carrier logo transferred over to my iPhone 3g! So, while we may not be able to jailbreak it just yet, if you had a custom carrier logo previously, you can get it once again. Cheers.
