Yesterday we reported that the Dev Team updated its new RedSn0w software to 0.9.6b4 and that it can now jailbreak iOS 4.2.1 that was released last night.
Well we are calling out to all those that have tried the new RedSn0w and if it went smoothly or you found problems, Redmond Pie and iDB have much more information about the new RedSn0w update so please do visit these sources.
Other devices will get a tethered jailbreak and this means that you will have to connect your iPhone and launch RedSn0w every time you reboot, please be aware that if you wish to unlock your device you should not use RedSn0w because it will update your baseband, iDB do suggest you wait for PwnageTool.
Please do let us know if you have had problems with RedSn0w 0.9.6b4.
