Help with unlocking the iPhone 4 (please)?!

Hi!

Okay, I have been a complete tit.

Here's the deal: I am with Vodafone: I just upgraded my 24 month contract (with a BlackBerry) to a 12 month sim only contract for the iPhone 4 (I don't want to be tied in to 18/24 months again). I order the iPhone with Vodafone. However, 6 days later my order is still in the 'credit check' status (even though I was paying for the iPhone outright?!) So...sat with a micro sim that I can't use and with growing impatience: I find the iPhone 4 (32GB) on Orange (pay as you go) with free next day delivery. I cancel my Vodafone order, call Orange and ask if it will work with my Vodafone sim, the girl says 'it should do'. I place the order, receive my iPhone today and...sim 'isn't supported'.

Does anybody know what I can do to get my Vodafone micro sim to work in my Orange iPhone without jailbreaking it (or point me in the right direction of where to look)? (I'm terrified of breaking the iPhone!) Orange tell me I can't unlock it for 3 months!

Thanks!

 

Right, okay. I just e-mailed Orange about returning the iPhone and am waiting on a reply. I gave them all the details and told them I would happily keep the phone if they could unlock it for me (worth a shot!) I'm contemplating jailbreaking through impatience now (and the fact that I have an iPhone 4 right in front of me just crying out to be used). I just really don't want to bugger it up and cause an irreversible crash of some sort seeing as I've bought the phone outright. Sigh.
