Can I jailbreak an officially unlocked iphone 3G (Brazil/France)?
I have a legally unlocked iphone 3G 16GB from Brazil. It was unlocked via itunes after my requesting so from the carrier (Vivo)
I would like to jailbreak it, mainly in order to run frings over 3G and thus making cheap calls from Brazil to the US or to Brazilian land lines.
Now I wonder, the unlock depends on a special firmware download? Being that the firmware downloaded for Pwnage would not be unlocked? Please explain!!
So I have to chose: either jail break or unlock?
If so, after a jailbreak, can I always reset the phone via itunes, if I want to have it originally unlocked as before?
Just some curiosity: nobody managed to copy whatever apple does to unlock iphones via itunes? some packet sniffer or man in the middle in the itunes usb connecting cable? Probably there is some strong encryption and some imei dependent information in there?
Anyone has deep understanding of the legal itunes unlock? jailbroke such a 3G phone?
from my rudimentary understanding, apple probably loads some special version of the firmware or a patch to unlock the iphone.

So it is quite likely that this will lock the iphone, that it will undo the official unlock
Of course people with deeper theoretical understanding or actual practice would know better.
Where are the experts? or the Brazilians or French?
