Don't be surprised if you can't GET to that path through apple config for whstechy's solution (which DOES work), however, you may have to first unhide your user library. It is hidden by default in models that come with Lion... even from configurator. Once you unhide your library, THEN you can direct AC directly to the iOs file.
My AC installs won't update the iOs without whystechy's solution, and when I talked to enterprise, that acted completely clueless to the issue. Oh.. an just as an FYI, if you are running both iPad 2's and 3's in the same cabinet, you will need to use the first part of whstechy's solution (downloading the iOs) for BOTH types of iPads or you will get the message 'unable to locate iOs file' in Apple config because it needs a different iOs file for each type of iPad.
Anyone find a solution to jibjc's issue? I am still having that one. Works sometime but bugs out on others. Enterprise told me it had something to do with 'manufacturing differences' but I don't buy it.
Thanks all! Couldn't do it without you!
