Nah, it doesn't imply that. I just meant that after owning every iPhone (except the first) and knowing 20+ relatives and close friends that own one, I have never had that happen or heard any of them mention it. And usually when they have a question or issue they'll ask me because I have used them for so long.
I know people have different kinds of issues but that's just one I didn't know of. Typically if the phone locks up, all it takes is a restore to fix it.
