From submitting a bug report to Feedback: Investigation complete - Unable to diagnose with current information There's no hint about what extra information was needed. We're stuck here - Dev Forum says report the bug (done), I rang Customer Support - they can't reach into our Dev account to examine it because theyre customer-side not dev-side, and Feedback Team says not enough info. Who I need to contact? Maybe a phone call to the Dev team so I can fully explain the problem?

FB14936662 is the ticket reference. Still awaiting a respsonse from there.

Ditto: DVTAssertions: Warning in /Library/Caches/com.apple.xbs/Sources/DVTiOSFrameworks/DVTiOSFrameworks-17705/DTDeviceKitBase/DTDKRemoteDeviceData.m:371 I've raised a bug report. I'll let you know if I get a reply. You may also want to submit yours. The more the merrier...
