Oki doki, here are the answers to your questions:
1) The whole media size, here on my Windows Lap Top, is arround 25 MB including bytecode. But discovered that it actually could be less because I forgot to delete some unused sound files
2) The process of generating an iOS was straight foward and well explained by the guides, existing in the AppGameKit help. Just follow this steps and it works
Actually I needed arround 2 hours to got the Xcode part done, even I had some problems to remember how to do all the codesigning stuff... But there are good help docs on the Xcode developer site too.
3) Actually submitted the app on last friday. Taking in account that they do not work at apple over the weekend.... it took not that long to got the app approved on yesterday evening. If you count the real workdays, it took apple just friday,monday,tuesday and wednesday, ergo 4 days for approval
Cheers!
Stephan
