These logos were designed to fit the display of a Sony T68i phone but they can also be used as backgrounds on other phones by Nokia and Samsung. The logos are all free but in order to use them, you must have access to an online MMS service. Some phone companies have a free MMS service that allows you to send your own logos to your phone with an MMS message. The animated matrix code was created by Matrixforever and works fine. Just remember to choose it as a screensaver and not a background.
