Problems unlocking iphone 4 on itunes help !

[Anonymous]

HI!

I have had my iphone 4 successfully unlatched with o2, as I now live overseas and need to use a foreign sim. The next step i was told to insert the non-o2 sim, plug into itunes and will receive prompts to complete the process, however when i plug it in nothing happens on itunes!

And the phone still says 'locked sim', and asks for a 3 digit unlocking pin.

Please let me know if yuo can help, greatly appreciate it!

Thanks

Hi,

Is the alternative network sim activated ?

If itunes is not telling you its now unlocked you may have to ask for the unlcock again.

Are you still in the Uk.

Actually no it's not unlocked ! Should I tryt o unlock the sim, then plug into itunes again and give it another shot?

I am no longer in the uk, i'm in france.

thanks for your help!

The process is :

Request the unlock from o2 via the unlocking form.

They e mail you to say the unlock has been completed.

You insert another alternative Network Sim card in the iphone and hook upto itunes where the process is completed.

I am having similar issues with it saying 'no service' when I first turn the phone on, but 'invalid SIM' when I turn Airplane Mode on, then off. I've had a text from 02 saying 'iphone is now unlocked'.  I've plugged the phone into my laptop to try and unlock it, but I am getting nothing other than it trying to sync with iphone.

The iphone is on O2 but the SIM inside is on Vodafone.

Any ideas what I can do?

Thanks.
