The Info.plist file acts as the configuration manifest. In the context of Angry Birds Epic, this file defines critical parameters such as:

Even if you find a working IPA, Apple regularly revokes the enterprise certificates used by sideloading tools. The app may work for a few days or weeks, then suddenly refuse to open—crashing immediately upon launch.

After downloading, you can inspect the IPA file by renaming it to .zip and extracting it. Look inside the Payload/ folder. If you see an executable named Angry Birds Epic and legitimate asset folders (scenes, fonts, sounds), it’s likely valid. If you see extra .exe or .bat files, delete immediately.


You no longer need a jailbroken iPhone to install IPA files. Apple allows sideloading via developer tools and signing services. Here are three proven methods.

The _CodeSignature folder contains the digital signature of the application. For an acquired .IPA to function on a non-jailbroken device, this signature must be removed or replaced via a process called "re-signing" or "sideloading" using tools like AltStore or Cydia Impactor.
