Comment 28 for bug 877440

New upgrade to oneiric. idevice_id correctly identifies device ID as "JimmyG's iPhone" and if I plug the iPhone4 (iOS 5) in with it in a locked state I get a dialog telling me that it is locked and should be unlocked. The instant I unlock it, I get the "unhandled lockdown error -4" immediately. idevicepair unpair/pair does not work. I get the "QueryType failed, error code -256" error. So, idevice is communicating with the device, as is the OS for I see other information collected; e.g. in the syslog are multiple entries regarding the iPhone as a USB eth device:

So, again, there is significant communication between device and computer, but the damned lockdown error persists no matter what I attempt.

I'm quite willing to support any effort to trouble-shoot/debug this issue, if someone will provice guidance on what I can provide to you. As I'm apparently not alone in seeing this -256 error (there are several reports on forums.ubuntu.com and forums.linuxmint.com and on this bug report).

This has been very, very frustrating. I saw so many reports that the latest libs in oneiric "solved" the issues that I today spent the hours necessary to backup and then upgrade to it. Only to have the exact (!!!!) same errors with oneiric that I had with natty.
