Jailbreak after official o2 unlock???

From what I understand if the phone is unlocked by the carrier, then it remains unlocked forever. Even if the phone is jailbroken.

 

Yes its fine i have the same phone unlocked by apple and now jailbroken wit hno problems phone works just the same

 

Anyone know of any problems doing this unlock on a jailbroken iPhone 3G?

 

No problems, I have a jailbroken 3GS and unlocked fine and my friend unlocked his jailbroken 3G with no problems.

Thanks 02

 

Hi there,

I have a jailbroken 3G on 3.1.3....and I am locked out of the new baseband 5.12.01. Will the official o2 unlock work when my iphone has already been jailbroken?

 

worked fine on my iPhone 3G I just removed blacksn0w unlock and sync'd and got the unlock message whilst still jailbroken

the O2 unlock is not baseband specific it will unlock your phone regardless

 

Yes.

 

No, you have a phone unlocked by your carrier using Apple's servers

 

I always wonder why can't the dev/hackers find out how carrier unlock iPhone (ie. forever) that was once locked to specific carrier. I mean, if Apple/carrier is able to do it with a software update then it must mean that there's some sort of way to do it.

Not that i care much about it because i have an officially unlock iPhone. Just wondering.

 

I wish it was that simple.
It is done on the Apples servers side not on the phone.
