Pretty Sans Serif

Hi folks!

Any help with this pretty sans serif?

Thanks!

It is pretty.
Myriad light semi-extended?
Kyrial sans light?
It's got that humanist/Frutiger vibe, but rounder, more extended, taller x-height...

As previously suggested by monmeehan and probably too much obvious, I would have said Myriad (Semi Extended Light). I assume the official former logo was set in Myriad. Makes me also thinking to http://Segoe (could be the one if these captures come are related with Windows Mobile). Another similar is Interval Sans.

Is it some form of http://Segoe? Are those screenshots of Windows Mobile UI?
