What are .ipa Files ?


Many of you may not know what are .ipa files . Well the “.ipa” file extension stands for iPhone Application Archive. It stores the iphone app for the App Store . These are encrypted with Apple DRM [Digital Rights Management] technology to run only on a iDevice like the iphone 4 and itouch 4. Each .ipa file is compressed in a manner that it can only be installed on an iPhone, iPod Touch, or iPad and not on the PC [simulator].

Possible Solution :

Launch Installous. Add the source “” and go through their source and download the jailbreak app AppSync . Make sure that you download the version of AppSync that matches the iphone firmware you are having. This should solve your problem .
