Hi, Given that the prices in the US (Amazon for example) are much lower than the unlocked version available in the UK, I might try to get the N900 bought there and sent over by a friend. Would the difference in models affect my experience of 3G/HSDPA networks in Europe if I used a US model? Also, is Nokia differentiating firmwares based on product codes like with Symbian, or is every model able to automatically receive firmware updates?
