Touch 4G can be downgraded from iOS 6 to iOS 5 using latest version of RedSn0w.
The iPhone Dev Team has followed its announcement on a major update for RedSn0w 0.9.15b1 (for A4 devices - the iPhone 4, the iPhone 3GS and the iPod Touch 4G) with an update for RedSn0w 0.9.15b2. This update is believed to include bug fixes for the iPhone 3Gs.
A blog post reads: "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 restores). Don't forget you can add some pizzaz with your own boot logo or a nerdy verbose boot."
In addition, with this version (and using saved SHSH blobs (Windows / Mac), iPod Touch 4G users can downgrade from iOS 6 to iOS 5.x; to downgrade, follow this tutorial.
IBTimes UK reminds readers it will not be held responsible for damage to the device during installation. Ensure you have backed-up all important data and the battery of the device carries at least 80 percent charge.
