Incase you were wondering why Geohot used a userland exploit from Comex to make Limera1n untethered, it was because he did not wanted to waste his untethered version of bootrom exploit which seems to be more powerful than the exploit used in Limera1n. Both Comex and MuscleNerd has confirmed that Geohot has in his possession a new untethered bootrom level exploit which can be used to pwn future iOS devices like iPhone 5 and iPad 2G for life.
