I've activated my iPhone with Jon's method, and It works fine ;-).
Though, I have a problem with the ITunes. When in run Itunes and connect my iPhone, this appears unde the device's tab in iTunes; but without any content, so I can't syncronice my calendar, music, etc...
Is this "common" in the JMHP ( Jon's Method Hacked iPhones )? If not, how can I solve it?. I've already tried with the original iTunes and it doesn't work.
