Many jailbreakers that had kept a close eyes on the jailbreaking scene should know that right now, idevice with old bootrom can be jailbreaked untethered. For new bootrom idevice, it can only be jaibreaked with redsnow TETHERED.


Comex and the iphone dev team had came out with a way to jailbreak untethered.
The iphone dev team had way to make use of the developer built 4.2b3 SHSH for untethered while @comex came out with a better way which does not even users to restore it.


Comex had initially stated that his exploit will be released on the eve of Christmas. But today, @comex tweeted that he might missed his due date.

Does this means that he would not be able to push out the jailbreak by this christmas?

Let’s wish comex and the iphone dev team good luck as we wait for the jailbreak.
