I think the Jughead bomb may be used to destroy the energy beneath the Swan just like Daniel Faraday planned. The catch? It won't happen until "Live Together, Die Alone" when Desmond turns the failsafe key. After all, the energy ceased being a problem after Desmond turned the key. Maybe Desmond destroyed the energy that day, and the only method we know of to destroy it is as Daniel said, with a hydrogen bomb.
I think Jack and Co. will succeed in bringing Jughead through the tunnels to a point below the Swan, but not in detonating it. Somehow, the leak that Kelvin spoke of will occur, also known as the incident. This will stop Jack from executing his plan, and simultaneously provide the reason for the DI to set up the computer to discharge the electromagnetism every 108 minutes. As a failsafe, they will rig up Jughead so they can detonate it if someone ever fails to push the button (they'd be understandably reluctant to do so until absolutely necessary).
It could also be, that the only way to detonate the bomb without taking out the entire island is do it after the electromagnetism has built up to such a level that it would contain the blast. This might explain the Swan imploding instead of exploding when Desmond turned the key.
The Swan station's countdown timer shows a set of hieroglyphs when it reaches zero. Damon Lindelof has stated that the hieroglyphs represent the word "underworld" (source: lostpedia). The fact that "underworld" is displayed whenever the timer reaches zero may mean it is the only safe time to turn the key and detonate Jughead, who is currently residing in the "underworld" of the tunnels. This is somewhat supported by the scene in "Live Together, Die Alone" where Desmond finds a drunk Kelvin contemplating turning the key. He's down there just as the clock is almost down to zero but Desmond comes along to enter the numbers. Kelvin may have needed to wait for zero before turning the key (though it appears he did chicken out in the end regardless).
That's about it I guess. Jughead = Failsafe. Can't wait for Wednesday!
