The iPhone Dev Team has released new version of redsn0w that allows users to jailbeak their A4 devices running iOS 6. The new jailbreak is semi-tethered and will install Cydia automatically (no need to install it manually via SSH).
Check the video tutorial after the break.
The new redsn0w 0.9.15b2 also brings some bug fixes.
From the Dev Team's Blog:
Update #1 (Oct 15): 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 redsn0ws Jailbreak step (no need to restore). Don't forget you can add some pizzaz with your own boot logo or a nerdy verbose boot.
