What are the chances of getting a deal out of Voda for the iPhone? I know apple dictate the plans themselves to the networks, so theres no chance of getting extra minutes etc. But I was wondering if retentions have the power to give you other freebies e.g. M&S vouchers (like Sky and others do) or a few months free mobile broadband service?

Ive been with voda a number of years now, and my most recent contract ended two months ago and havent persued renewing it yet as ive been toying over the iphone or desire.
