I know about the tools since I just named them! and I know about the process. What I don't understand is the difference between both tools.

Give me a little credit here and stop trolling.
Okay, Limera1n is not an option here. As a side note, the Greenpois0n folks software is just as good as Geohot's. Plus, they update it. I use Greenposi0n given a choice.
