All IPAs are tested before being added to the repository. This may take several days. If a version is unstable or doesn't work, it won't be added.
Use classic with :
- SideStore (recommended)
- AltStore Classic
- LiveContainer
Use patched with :
- Feather (recommended*)
- ESign
- KSign
- TrollApps
*You can easily install an older version with long-click with Feather.
- AltStore PAL
SideStore : 3 apps and 10 AppID limit without LiveContainer. PC needed for first installation. Hard to install.
Feather : Need to buy licence from Apple Developper Program or certficate from a signing service. Avoid KravaSign, Signulous, FlekSt0re and AppsTesters.
Entreprise certificates (aka "free certs") are not recommended. This method is not reliable, violate Apple's Terms of Service, and may get your iDevice blacklisted.
