Can someone tell what's the difference between MB and MC iPhone 3GS ???
I've seen many MC 3GS with old bootrom and many MB with new bootrom... and vice versa....
Is there updated hardware in MC models ? I heard about people not beeing able to jailbreak their iPhone 3GS with old bootrom because it's an MC version !?!

so is it related to bootrom version ? to hardware update ? .....
