You know that unlocked iPhone T-Mobile has to sell in Germany? Right, the one that costs 999 instead of 399 with contract. Well, if you're Debitel, then you make a bid for the iPhone non-exclusive by offering a 600 sign-up bonus (to bring the cost back to 399) on a network of your very own. Of course, visual voice mail is a no-go and there's no mention of unlimited WiFi, but at least you've got the iPhone (and a fat Debitel contract, presumably).
