Why my iPhone's name remain 'Generic'?

Hello all.

When I set up my new iPhone 3GS, I gave it a customized name, e.g. "My iPhone 3GS"

But I found out when I
- tested 'Find My iPhone' in MobileMe Online and
- in iPhoto

*In both cases, my iPhone 3GS is called "iPhone"*; Whereas my old iPhone, is still named after the name I've given it.

I know it is really not a big deal, *but why the name remains "generic"?*

Thanks
