I contacted Vodafone UK re buying a PAYG iPhone and getting a micro SIM for my existing contract. This is the response:
'I appreciate your interest in the new iPhone 4G.
As of now there is no update that we are going to launch the iPhone 4G on Pay As You Go (PAYG). We are going to launch the iPhone 4G on Pay Monthly contracts on 24th June 2010. The iPhone 4G is only available through upgrades or for new connections and we'll be providing a compatible SIM at the time of upgrades or new connections.
I trust this helps.
So it looks like I'll have to get my stanley knife out............! Pity - or go with O2 (slow 2).
