You can always count on the folks across the pond to have crazy pricing options for their phones. Pricing for the iPhone 4 on Orange UK range from a completely free iPhone 4 16GB with a £75 ($110) monthly plan to £570 ($843) for a iPhone 4 32GB on a pay-as-you-go plan to every other price point imaginable in between. We know this is pretty much par for the course for you British, but 28 different pricing options is a little overwhelming for us.
Orange UK hasn't started taking pre-orders but for what it's worth, they make no mention of the White iPhone 4 being unavailable. [Orange]
