Unlocking iPhone 4 from orange network?

I bought an iPhone 4 which is on the orange network I rang and asked to get it unlocked (paid £20) they said it would take up to 30 days and have to wait on an email with a code thing is the sim in the phone is not active and was wondering does it need to be to be unlocked

Orange need to send you a PUK code which unlocks the phone, they have the code already… So get back onto your provider and find out why there is a delay

If You wish to use other network Sim card, You should unlock it. If you are using Orange Sim card in it and it is showing " No service " it means it is Sim activation issue.
