the same result you get, if you go to the UK-shop, put the pre 2 into your basket and change the language afterwards to german.
You than have the german pre 2 in your basket and may continue to check out.
by the way: why not pay 499€ for the pre 2?
in germany the situation have changed, you may now decide, wether you wanna pay for the phone with your monthly rate or without that and to pay it directly.
to buy it directly and have a much lower monthly rate is mostly the more economic solution.
but still everybody can decide and the carriers will offer the pre2, i am sure...
