TiPb Jailbreak Genius
Why you should use greenpois0n if you dont need hactivation!
For users that can activate via iTunes:
Limera1n installs a hacktivation dynamic library (.dylib) to /usr/lib, no matter if the device is properly activated by iTunes or not. This is lazy and can pose some issues (such as Push Donor users having to restore their device). It's recommended to properly remove this dylib only if you can activate via iTunes.
The instructions to remove the dylib can be found here:

However as this is somewhat advanced, my recommendation to new Jailbreakers that can activate through iTunes is to use Greenpois0n...
If you cannot activate through iTunes and need Hactivation, then this does not apply to you and you will need Limera1n's dylib...
