An internal Apple memo has leaked highlighting how Apple would like Apple Store employees to respond to complaints about the fact that holding the new iPhone 4 may result in it losing some or all signal bars. The memo almost-but-not-quite confirms there's some kind of problem, but employees are urged to downplay the issue by highlighting that the phone's "wireless performance is the best we have ever shipped" (yeah, well, at least when it's not being touched). Consumers are still being told they're essentially just holding it wrong -- but that a case might help, and employees are told that under no circumstances are they to give complaining customers a free Apple "bumper" case (which retails for $30) to help resolve the issue.
