Hello to all

'Pollo' was actually started by my mum, who bought the Kindle 3G with keyboard for me as a Christmas present - which I loved, by the way.
Anyway, she bought it online amazon.com and had it delivered to the USA, making me guess it uses AT&T... However we registered it on my mum's main account: .co.uk
Thing is, I live in Italy, and while in Milan my 3G worked, now in Rome my 3G only works with Wikipedia and the Amazon online store. It says something about 'local restrictions'.
Is there some way I might've gone wrong? What to do?
Second question:
If I buy a french (for example) dictionary on amazon, how do I make it accessible for french books?
Thank you all in advance, and have a nice end of 2011 and beginning 2012
