Acer iconia tab region changed?

Hi,

I recently brought my acer iconia a500 to Spain but since I have come back I am getting network problems in a number of places. There are a couple of games which throw a network error when trying to download new content and most annoying is the fact that youtubes 4ODpage is showing the videos as not available in my region. These videos play fine on my netbook.

Could being in Spain have changed my region anywhere in the settings?

Thanks
