A tweet from @Comex stated that he mite be unable to complete the Untethered Jailbreak which was said to be coming on Xmas.
@Comex: I think I’m going to miss my Christmas Deadline..
Comex’s untether is more extensible and should not require access to the developer only 4.2b3 IPSW; thus, it’s suggested that users wait for his.
Any ways the Dev Team got the Backup Plan working and they may release that.
Lets not loose our hope in the Untethered Jailbreak. Lets hope any one of them either @Musclenerd or @Comex comes with up an Untethered Jailbreak.
