Usually when I get apps they come in a .ipa file. However for some reason nowadays when I get them they appear to be .zip files but their name ends with a .ipa (not the actualy file extension). I'm just confused on why the sudden change has occurred and if there is any way I can make these files into actual .ipa files so I can add them to my library to sync afterwards. I realise with these kind of zip files I need to SSH and send them to my iPod. But I'd like to know if there is any other easier ways like the .ipa stuff I usually do with these files.
