i do not think this form is for actual Booking the model. they do not seem to be asking you to pay a booking amount. without that this is just a subscription form to get updates (and possible spam) on your mail account.
At that price point, wouldn't the Galaxy SII or the Sensation be better options? The Lumia 800 has a single core CPU, 512MB RAM, no front facing camera - this puts it at a disadvantage against the other two flagship phones. Also, once ICS starts rolling out to more Android phones, that'll be yet another disadvantage for the Lumia.
