How to create Backup Firmware iPhone 3G? And Restore Future?

Question

Hello, 

 

iPhone 3G unlocked and after I have done Free Jailbreak (For programs). 

 

When iPhone?, You can copy the firmware you have installed 

(In your guts) creating an image that is saved on the PC? 

 

And then does not operate to restore this flow created firmware (which is already unlocked and released)? All this without damaging anything. And so prevent iTunes you unlock and release (As if the process fails). Who knows what Apple can do ... 

 

And what would be done without damaging the device? 

 

Right now neither play nor grazed, camaraderie with this ... 

 

Thanks for helping me with any questions in advance.

Answer 1

You can not make a copy of firmare directly also makes no sense that you have on any firmare web for download without any problem. 

 

The 3G iphone, this so that apple discontinued or look for, so you do not have problems.
