Difference between MBP MB488LL/A and MB134LL/A?

[colickyboy]

Hi,
MBP model numbers MB488LL/A and MB134LL/A appear to have the same specs. The latter number appears to be "official", as I see it listed in the MBP wiki page but the former number is not listed although it is sold in some 3rd party Apple retailers.

What is the difference between these two models?

I think the MB488LL/A is glossy and the other isn't.
