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.
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.
