So Apple are giving away free iPhone covers to all who complain about the signal issue!
Free bumper case anyone? lol On top of that there also offering refunds until the end of September for anyone not happy (bet the mobile networks love that idea).

I suspect a tweaked hardware model will probably be in the works for late this year, maybe as rumoured some sort of an internal bumper...
