No way I believe any of these rumors, until Tim Cook from Apple is on stage himself, showing off the new iPhone.
Last year, just a week before the iPhone4S release, reports were coming in like crazy of a whole new designed iPhone, they have even had leaked cases with the supposed bigger and new design iPhone5, from Case-Mate, and BGR was screaming from the rooftop that a whole new phone was coming out.
Look at how wrong they were, and that was news from just days away from the official release, and they still had it all wrong. Now we are months away from release, so no way these leaks are correct.
