iPhone 3g's that are factory unlocked (aka legally unlocked) are updated with the same firmware file as any other iPhone but what allows them to stay unlocked?
I have not played around with one myself, but plan on getting one to see if one can be used to unlock others.
firmware is same but att phone is hardware locked. To unlock you would need to move one chip which means moving whole pc board which does not make economical sense unless maybe your att phone is broken because of your fault not fuctional, i.e. you might designate one phone for parts
iTunes send a combination of NOR ID, SerialNumber, ModelNumber and IMEI to Apple servers, they respond with the NCK token and unlocks the baseband, it all about your modell. No magic behind.Quote:

So its all a matter of Apples database, every iPhone can unlocked by his NCK code / token. All phones the same, no differences in hardware or baseband, they only have different IMEI's, NOR ID's and Serials.Quote:

Please, if you are making crazy assumptions, put a couple "I think..."s or "I'm not sure but.."s in there so noobs don't actually listen to you.
you do not understand. These phones are simply marked in database to allow other carrier sim card. And phone does retrieve database query NOT only thru itunes. Phone is not permanently unlocked and T-Mobile/Apple does not offer such service for free.Quote:
