By Mark Prigg PUBLISHED: 08:19 EST, 15 February 2013 | UPDATED: 11:48 EST, 15 February 2013 Apple has given a rare glimpse of its top design design lab where the iPhone and iPad were developed. Sir Jonathan Ive, the London-born Senior Vice President of Industrial Design for Apple, gave the show a rare glimpse into his lab - although was careful to hide any products. Instead, he used Apple's expensive milling machinery, usually used to create product prototypes, to make a giant Blue Peter badge for the show - as it honoured him with a gold badge.
