iPhone Dev team has once again jumped to the rescue of A4 jailbreak users with the release of a major update for Redsn0w. The new beta update - Redsn0w 0.9.15b2 - adds bug fixes for iPhone 3GS and iPad users, besides incorporating a new re-restore functionality.
Here's what the iPhone Dev team's blog reads about the new Redsn0w update:
"Version 0.9.15b2 fixes a few issues for 3GS owners: old-bootrom awesomeness is no longer forgotten directly after a restore, and iPad baseband upgrade/downgrade support is fixed (same production date cutoffs apply!). If your 3GS is currently tethered at 6.0 even though you have an old bootrom, just re-run redsn0w's Jailbreak step (no need to restore). Don't forget you can add some pizzaz with your own boot logo or a nerdy verbose boot."
In other words, iPhone 3GS users with older BootROMs need to re-run the jailbreak steps to restore untethered jailbreak capability on their iOS 6 jailbroken (tethered) devices.
