K, so I was hacken my iphone and crap and then I was liek, "Ima gonna restore my phone for now cause my jailbroken crap is screwed up." So I restored and I was legit again... 3 or 4 weeks later I try to text my friend and all the sudden I get the "error sending message" error thing. And from then on I couldn't send text messages. I could go into more depth but I don't feel like it. So naturally I go to the apple store and get it checked out and the person and they were all confused and crap. So while we are sitting there wait for the guy to just say "ok lets go get a replacement" (it took him like an hour or so to find out that my problem was unifiable) my dad asks me if I have ever hacked my phone before. I was liek "ya of course." And about that entire time he is sitting there explaining to me that jailbreaking causes perminate damage and then he confused it with unlocking and some other weird conversation points came up. Anyways, he apparently thought that modifying the firmware (through quickpwn) was a perminate thing that could not be reversed. I think he is still thinking of unlocking which is completely different. Either that or he thinks I'm modifying the bootloader. So can you clairify the above?
