Q: IPHONE 4 UNLOCKING PROBLEM ORANGE TO VODAFONE NETWORK

Hi

My problem is I had finished my contract of 24 months with orange/EE & payed £20.42 to wait for a confirmation email that did arrive after 2 weeks with unlocking process via iTunes.

So I wanted it unlocked so it could be used with a Vodafone microsim as a gift to my  dad so I bought a new Vodafone micro sim because I had to order a new microsim with all my dads details on it &  I did what the orange email said in steps but I (never got a congratulations your iPhone is unlocked) message but I noticed it did say Vodafone uk network on top left of the iPhone 4 screen.

But the Vodafone microsim was not the number I wanted as Vodafone had to change all the details from a standard size sim to a new micro with all my dads details as he wanted to keep the same mobile number so seeming that it was showing the Vodafone network signal & all working I finally received my dads  new Vodafone microsim with all his details etc that was on the standard sim that was in my dads old phone but when I ejected the Vodafone microsim that was working  I bought that was brand new & like I stated was working on the iPhone 4 & swapped it for my dads new micro Vodafone sim All I get is "NO SERVICE" So I went through the exact same steps on the email for unlocking my orange locked iPhone 4 again  as I did with the first voda sim but I get " No service ". I'm sorry to bother you guys especially XMAS day but its a gift for my father today as it's his Vodafone number he wants to keep on the sim they sent so I phoned Vodafone & they said the sim needs activating & could take 30 mins to 24 hours. But it's been over 24 hours & Ive turned the iPhone 4 on & off but still no service plus I reset network settings & rebooted the iPhone a few times

It must be unlocked because  the first Vodafone microsim that I bought new recently  worked but its strange & extremely  frustrating that my dads new Vodafone microsim still says. "NO SERVICE"?

Would you be kind enough to help me if you have any idea what I've done wrong or is there anything else I'm supposed to do or could do to get this other new Vodafone Sim working. Sorry to bother you guys but you seemed to know a lot about unlocking so i thought I'd ask you. If you can help in anyway I'd be so very very grateful as I'm running out of time  

THANKYOU

Merry Christmas & Happy New Year.
