Iphone 4s better battery life on ios6?
Jailbreakers will be pleased to discover that iOS 6.0.1 can already be jailbroken by using existing versions of Redsn0w. Currently, only the iPhone 4, iPod touch 4th gen, and iPhone 3GS are supported, and you’ll have to point Redsn0w at the older 6.0 IPSW, but otherwise the process is pretty much the same as any other recent tethered jailbreak. The simple walkthrough below guides you through the process, but the Redsn0w app itself also is fairly explanatory these days.
Before beginning, it’s a good idea to perform a manual backup, this lets you easily undo the jailbreak without losing anything. Use iCloud to backup manually or go the traditional route with iTunes, but don’t skip this step.

Get the latest version of redsn0w (https://sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.15b3.zip?attredirects=0&d=1"]Mac OS X[/URL]) (Windows)

Launch Redsn0w, click “Extras”, then “Select IPSW”, and choose the iOS 6.0 IPSW file you just downloaded, then go back to the main Redsn0w screen and choose “Jailbreak”
Follow on screen instructions to enter DFU mode by holding the Power button for 3 seconds, then while holding Power also hold the Home button for 5 seconds, finally release Power button but hold home button for another 15 seconds, Redsn0w will notify you when DFU has been successful
Be sure to check auto boot in Redsn0w to automatically boot the device tethered upon restart, if you missed that step go to the primary redsn0w window and select “Extras” followed by “Just Boot” to boot tethered
When iOS reboots you should find Cydia on the home screen, signifying the jailbreak was successful. If you don’t see it or it doesn’t launch, you probably didn’t boot tethered, which is required. The whole tethering thing is the primary downside to these types of jailbreaks, as you’ll need to connect it to a computer with Redsnow each time the device reboots or runs out of battery.
If you decide to undo the jailbreak, just connect the iPhone or iPod touch to the computer and choose Restore, selecting the most recent backup stored locally or within iTunes.
