Why? It needs to be jailbroken to be unlocked.

Hi Annie,
I want to restore it back and make my iphone as unjailbroken.
Can you help me in this.

what i.Annie is saying is that if you want it unlocked to use on unofficial carrier then it will have to be jailbroken

[i.Annie]

Yes, that's exactly what I mean. If you want it back to unjailbroken, you can't unlock it anymore.

Hi,
my iphone is in jailbroken state with Firmware version 6.15.00.

My question is : can i restore my iphone and if yes what is the process?

[i.Annie]

Yes I understood your question the first time. Don't you need it to be unlocked???

[sam@27]

yes i need to unlock it again if its locked after restoring.
Can you please tell me the process to restore.

cheers,

You can only restore to stock firmware of 4.1 ( if you have shsh blob of 4.0 to 4.1, you don't need shsh blob for 3.1.3 or lower ) but your 6.15 bb will remain there, no way you can change that.
There is no way you can restore to stock 4.2.1 fw and you cannot have 4.2.1 unjailbroken.
If you want the highest fw but unjailbroken, you can only go for stock 4.1 with your already installed ipad bb.
Note : your iphone will not be unlocked if you do not want jailbreak as you have ipad baseband.

+1. like I said, if you want to unlock you shouldn't restore your phone to original settings. It needs to stay jailbroken.
