Who said so? All international Apple sites list exactly the same shipping dates (end of March, one month later for the 3G) as the US site. Jobs only said that international "data tariffs" might not be announced before June/July... as the device is not locked to a carrier, there is no dependence on special tariffs. Almost any GSM provider will do.
We have pre-ordered 150 iPads through our business rep and he said that sales in Europe will start at the same time as in the US. He is not allowed to tell us the date though...
I stand corrected then.
What are the prices in Europe? Or elsewhere?
