Signing and install FAQ
Common questions about installing custom PosterBoard wallpaper apps.
What is an unsigned IPA?
An unsigned IPA is an iOS app package built without a signing certificate. It cannot be installed as-is on a stock device; you must sign it first with a free Apple ID, TrollStore, or an enterprise certificate.
Do I need a jailbreak?
No. These apps use verified exploits or sandbox-escape techniques to reach PosterBoard data, but they do not install a persistent jailbreak, bootstrap, or daemon.
Which signing method should I use?
For most users, TrollStore or a free Apple ID with a signing tool like Sideloadly is enough. 3105 is the exception and requires an enterprise certificate for device functionality.
Is it safe?
These are research tools that modify system wallpaper data through non-public behavior. Keep a backup and use them only on devices and iOS versions you are prepared to test.
