According to MuscleNerd, Untethered Jailbreak for iOS 4.2.1 with RedSn0w is about ready. The New RedSn0w will not only jailbreak iOS 4.2.1, already jailbroken (tethered) users can use this new RedSn0w to re-jailbreak to get untethered support without any restore (all installed jailbreak tweaks will stay).
Note: This is a backup Unterthered iOS 4.2.1 jailbreak plan for those w/legit access to 4.2b3 IPSW. Comex will bring the original untethered jailbreak for iOS 4.2.1.
MuscleNerd: the backup plan for those w/legit access to 4.2b3 IPSW is about ready…again though, better to wait for comex
MuscleNerd: Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for “backup plan” 4.2 untether
MuscleNerd: it shouldn’t require a restore…just another redsn0w run. (That’s the goal!)
Comex is working on bringing an untethered jailbreak 4.2.1. This backup jailbreak requires 4.2b3 IPSW. A new code written by Comex also allows users to retrieve Photos and Files stuck behind an unfixable filesystem problem.
MuscleNerd: This latest @comex code also allows retrieval of photos+files stuck behind an unfixable filesystem problem…good stuff!
The iOS 4.2.1 jailbreak (untethered), if everything goes as planned, is expected to hit masses this Christmas eve. unlock for iPhone 4 baseband 02.10.04 / 03.10.01 is also expected in less than a month. We’ll keep you posted as soon as a jailbreak or unlock tool is out. Stay Tuned!
