Just as an FYI, when we received the iPads at PSA, they were not distributed individually by hand. They were all mailed to an address that we provided them (home, in most cases).
There was a process for picking them up from a base coordinator, but that took longer and was not the preferred method.
We had been told the same thing, that they were all sitting in the company HQ for months, but that was just a rumor. A fulfillment company had them all set up for us and they were shipped with the preloaded apps and custom setup guides for our needs.
There is a lot of junk on the iPads from AA, with a special app for all of the company and airplane documents in addition to JeppView. They was all preloaded.
