Each time Apple releases a new operating system, a beta version actually, only registered developers can start upgrading their devices to the new iOS. Now, with the iOS 6.1 Beta 4 released, many developers hurry to upgrade their iPhone, iPad or iPod Touch. What it great with the latest iOS is the fact that it comes hand in hand with a tethered jailbreak offered by Redsnow.
Just like the other cases, jailbreak iOS 6.1 is available with the help of Redsnow, but unfortunately, it is available only for A4-based devices such as iPhone 3GS, iPhone 4, iPad 2 and iPod Touch 4th generation. Those of you who own a newer device such as iPhone 4S, iPhone 5, iPad 3/4, iPod Touch 5th generation, will have to wait a little bit longer until jailbreak will be available on this particular build. That is what is great will all those older devices. Now matter what, you will always have a tethered jailbreak available at least, due to the Limera1n exploit, which is to be found in it.
As I mentioned earlier, jailbreak iOS 6.1 beta 4 with Redsnow 0.9.15b3 is available only for pre-A5 devices and it relies mostly on the older iOS 6.0 firmware in order to perform jailbreak. If you are already accustomed with jailbreak performed by Redsnow, then you will have no problem whatsoever regarding the tethered jailbreak for iOS 6.1 beta 4. The process is pretty much the same as the older ones. The only thing that is different is the fact that you choose the iOS 6.0 firmware and not a previous one. After this, you connect your device to a PC or a Mac and, with the help of Redsnow; you will end the jailbreak process only in a couple of minutes.
In the last part, I want to mention the fact that a tethered jailbreak means that you will have to reboot in a jailbreak mode each time your device runs out of battery or you power it down.
