... does not work in the US. So far, so uninteresting (for me ).

The question remains if 3G t-mobile works in Germany (or other countries, carriers). As the iPhone is sold by t-mobile in Germany it should at least work here, right?

I found 1 comment on the YS feedback page indicating that it works with 3G. Can anybody confirm?

T-mobile.US users: This is very probably absolutely meaningless for your situation, sorry.
