Sim card not from a supported carrier

I had received an email saying that they allowed me to unlock and that I have to follow this instructions

Dear Customer,

Please find the process for unlocking your Apple handset:-

Before attempting the procedure, please take a moment to read the following information. Please make sure that your iPhone is up to date the latest software version. This can be checked by connecting your device to iTunes via a PC/Mac/Laptop.

Please be aware that if you have used an unauthorised unlock on your Apple device then Orange cannot be held responsible for any errors that may occur, as this procedure will not only be unsuccessful, it may damage the device. If you have modified the software please update with the latest Apple approved version.

Apple devices differ from all other manufacturers in that there is no code required to enter into your device to unlock it. However Orange have requested on your behalf to Apple that your device be prepared for unlock and the procedure below advises how you can complete this process. Only handset’s that have been requested to be unlocked via Orange or other networks can be unlocked this way and the below instruction will not work on other Apple devices.

Apple Unlock Procedure

1)Insert a non-Orange 3G SIM card. This must be a network provider who also supplies the iphone/ipad.
2)Switch ON the handset.
3)Connect to iTunes using USB cable
4)Use the “restore” option within iTunes (located at the bottom of iTunes not the top)
5)The handset may then display: USB cable and iTunes icon.
6)Disconnect from USB then re-connect
7)Synchronise device with iTunes
8)Once synchronised a message will appear on iTunes stating “Congratulations, your iPhone has been unlocked” If using IOS5 this message will not show
9)Follow on screen set up instructions to enable new carrier settings

Your handset should now be successfully unlocked

Should this not show, please keep other network 3G sim in the iphone and restore the iphone via iTunes making sure all data is backed up first.

So yes they Orange Uk allowed me the unlock but I did all the steps and the message that appears in itunes when I want to syncronise is that "sim card is not from provided carrier" This message it also appears in the iphone when the sim card in in. This is a non orange 3g card as they asked me.

I have been waiting long to unlock my iphone because I live abroad the Uk and need to be able using another sim card and now it is this problem. Please can anyone help with this?

My provider Orange UK has allowed me to unlock my iphone and has send to me all the steps. WHen trying to unlock my iphone, it gives me this message error

" The SIM card that you currently have installed in this iphone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iphone. Please insert another SIM card from a supported carrier or request that this iphone be unlocked by your carrier. Please contact Apple for more information"

I bought a non Orange 3G sim card as they mentioned and there is this message. Anyone can help me to unlock my iphone?

THanks!
