I've got a locked phone that I can unlock for free. I realise to unlock the phone, I need to restore and "update" the phone. Now that 4.3.4 is out, can I re-JB (phone is currently JB'ed) using the custom 4.3.3 IPSW so that when it is restored and "updated" that it will give me the nice screen to tell me that it's unlocked? or have I missed the boat with working on 4.3.3? Btw, blobs are saved (whatever it does??)!
