1st Logo (2002-2005)
Visuals:
 * Startup: On a white background, the text "Welcome to" is seen on top. Each letter of TimesTimesTimes zooms out and fades in.
 * Shutdown: The top text now says "Goodbye", and the T-Mobile text now zooms in and fades out.

Variants:
 * In its early years, the T-Mobile text just fades in and fades out with a wipe.
 * Sometimes a URL can be seen below. There are two versions of this variant. One version has a chyroned-in URL. Another has the animation slightly modified. Some differences include the letter Times in TimesTimesTimes, and how the letters enter and exit the screen.
 * On some T-Mobile Samsung phones from 2006-2007, the startup animation has an error where the animation switches from the normal version to the slightly modified version with the URL. This occured on the very last frame of the animation.
