O.k. I'm really good at this stuff, but I'm not sure if this will work. Here's the story. My dad wants to use an iPhone, but his company only lets him use blackberry's. So.. he wanted to see if he could use an iPhone and just not let his company know. So he tested it in a friend's non-jailbroken iPhone and his company knew and sent him an e-mail saying he can't use an iPhone and he can only use Balckberry's. So.. if we were to jailbreak and unlock an iPhone would his company be able to still know or no? Hopefully someone can figure this out. I could just test it, but his company can technically fire I'm if he keep's doing this.
