Macworld.com – After Friday morningâs Apple press conference about the iPhone 4 and its antenna issues, Apple executives took a small group of journalists (11 all told, including myself) on a tour of the companyâs wireless-testing facilities. We were, the executives said, the first outsiders allowed into the area, a spot off-limits to most Apple employees. Even our escorts from Appleâs PR department said they hadnât been in there before.
