Hello fellow iPodTouchFans! I have an question about the .ipa files, actually 2 questions. One: On my mac, when I download an .ipa (no, not c****** apps but for example free appstore apps), after I downloaded it, it shows up as an folder with the itunesartwork and the .app in another folder. How do I prevent this from happening, and put the .ipa into iTunes like in Windows? Two: Does the size of an .ipa change if put on iPod through iTunes? I need to know this in order to make a decision between the 8Gb and 16Gb 2G Touch. What I mean is: on the pc it is an .ipa file (some sort of zip thing), but when I put it in iTunes, will iTunes unpack it and will it get larger then the .ipa? Example: on the pc it is 3 mb, but on the ipod it is 5 mb? Thanks already, I think the .ipa thing will help much people at making theyre decision!
