Iphone for jailbreak untethered or downgrade?

I have an iphone 4 that is currently on ios 6.1.3 and i i did a research that the jailbreak for that version tethered and not untethered. But iso 6.0 is untethered, do i have to downgrade to from 6.1.3 to 6.0? And how would i go about doing that?

Unfortunately, there's no way that you can downgrade from ios 6.1.3.So if you want to jailbreak your phone to ios 6.1.3, there's a tethered jailbreak available. Check this out for the jailbreak process at http://jailbreakhome.com

  • Untethered jailbreak for iPhone 4S IOS 5.1? I've heard such a thing doesn't exist. If that's the case, what should I do about jail breaking an iPhone 4S with ios 5.1? Should I somehow upgrade to 5.1.1 and do the untethered there? Or should I get the newest version apple has (probably not) and find or wait for a possible update for jail breaking there? And if I do somehow get an iOS 5.1.1 and manually update the phone to that, it won't mess anything up or erase my data, right?
