Finally it has just happened. If you bought an iOS devise (iPhone for example) in one EU country, you can use your warranty rights in another EU country!!!
Brussels, 25 September 2010, Antitrust: Statement on Apple's iPhone policy changes (Reference: IP/10/1175 Date: 25/09/2010):
...One focused on the "country of purchase" rule, whereby repairs service is only available in the country where the iPhone was bought, which made the exercise of warranty rights difficult for consumers who had purchased an iPhone in another EU/EEA country than their home country. The Commission had concerns that this rule could amount to territorial restrictions aimed at dissuading European consumers from buying iPhones outside their country of residence and so leading to a partitioning of the market...Previously, if people buy an unlocked iPhone in Italy while being residents of Germany, for example, they will be refused to get it fixed by warranty in Germany. They were forced to send devices to Apple Service in Italy (by providing home addresses in Italy) :(
Now it seems to be over and the cross-border warranty repair is now allowed. Let's see...
