We have a standalone mission planning computer with iTunes. Plug in your issued iPad and copy the .zip file to GoodReader.
Our AMC versions are supposedly locked down, not that I care to try to mess with it. They have deleted most of the apps, such as Safari and whatnot. It is a glorified Kindle right now (Phase I), but will soon have FLIP and supposedly eventually Facetime, work email, and lots of other things.
