Fixing Unknown error 0xE800000A in iOS Sync

The upgrade to iTunes 10.1 killed syncing my iPad. An 'Unknown error 0xE800000A' dialog was displayed. Searching Apple support, where the problem has occurred before without a fix beyond rebooting the device, and searching for the error on the web also didn't give a solution that worked.

Checking in the Console showed that iTunes couldn't write to a plist file in /var/db/lockdown; the file already existed and belonged to _usbmuxd. A quick Terminal session with:

cd /var/db/lockdown

sudo rm the file name

using the file name of the problem plist followed by a restart cured the problem.

[crarko adds: I haven't tested this one. I hadn't heard of this issue before but searching for it indicates it has affected a number of people, using any kind of iOS device.]
