iPhone hacker P0sixNinja just posted an update on Twitter saying his GreenPois0n jailbreak should be updated to support the recently released iOS 4.2.1 within a few days. According to his words, the jailbreak will be tethered or semitethered, whatever that means.

Earlier today, the Dev Team also gave us an update about the iOS 4.2.1 jailbreak and unlock saying they were working hard on it. Things look pretty good and it seems everyone will be able to get a jailbreak relatively soon. Older devices like the iPhone 3G and 3GS will most likely even be untethered and unlockable…

I want to remind you that as usual, if you rely on an unlock for your iPhone, you should not update to iOS 4.2.1 just yet. PwnageTool is always the preferred method to update.

    Tethered means that you need to plug it into the computer if it ever turns off and you wanna turn it on. Semi tethered is when it’s possible to turn off and turn on. But if you ever turn it on again after a turn off it wont have it’s jailbroken abilities. Only a regular iphone/ipodtouch/ipad/appletv. 🙂

    what is the point of a tethered jailbreak I always reboot my phone whenever i feel it slugish so this is pointless

  • JR

    Yeah, it’s not a good option for many people, but it would certainly be better than nothing.

    You know what, you all waited and waited for a couple months now for a new jailbreak and unlock, now there is one will come out (even though it may be tethered), you all already bitching about it. What a bunch of ungrateful users. It’s funny how you all begged every day: “please please hurry and give me a jailbreak and unlock…”, now one will come out, bitch, bitch, bitch… If you don’t like it, don’t use it, but quit wining…

      Bunch of ungrateful users? I only see one person here giving their opinion that it is pointless for them. A slight over reaction don’t you think?

        I get your point, but if you go back and read other blogs from this website relating to jailbreak and unlock, there has been numerous winings and complaining regularly, my oint is it doesn’t matter how much these developers provide us with all these great jailbreak and unlock solutions, there are some out there still complainning and bitching, those are the ungrateful ones that I am talking about.

    I was having problems unlocking my phone at home on my windows7 laptop so i took it the mall and had it unlocked the only problem is that its tethered so anytime my phone requires a reboot or power cycle i gotta go back to the mall. I tried the redsnow jailbreak but keep getting stuck at the reboot any ideas why
