iPhone 4 unlock after upgrade.

[Anonymous]

Hi, I've upgraded from an iPhone 4 and transferred my number onto a nano-sim for a 5, will I still be able to get the 4 unlocked? I have tried to submit the request, but it came back twice telling me that the information did not pass the security check... I assume this might be because the phone number used is now linked to my new IMEI number?

Any ideas?

You should really of got it unlocked first it might be easiest to get a payg sim and top up 20 make a few calls then submit the unlock but it will cost you £15

It's because you have not provided the correct password or tariff details.

It should still be able to be unlocked using the previous phone number as that should still be associated with the IMEI number of the iphone 4. Are you sure all the other details are correct?

Wouldn't the upgraded 5 iemi wipe the 4 off the system?

No, not if only a recent change.

How recent does it have to be I thought I read it changed almost straight away

I suggest do a swap my sim again and put the sim in your iphone 4 until it gets unlocked then go back to a new nano for the iphone 5

Yes you could do that

No need to sim swap. Just use an adapter as it should only take 24 hours but do need to enter correct details tho.
