If you are talking about The T-Mobile Today Plus theme, that them is only available on the 8100 (Pearl)

And I really don't take request for themes that are different that the ones I make, I might make changes to a theme if it's quick and simple, if I made a theme with all the request I have gotten in the past, I wouldn't be able to sleep. But who knows, I might make one simular to your request one day if that type of theme becomes available for 8300 series.
