Un-tethered Jailbreak for iphone 4 on iOS 4.2.1 is on its way . MuscleNerd tweeted few minutes ago about the expected release date for iphone 4 jailbreak on iOS 4.2.1 un-tethered . The current RedSn0w Jailbreak on iOS 4.2.1 is tethered, which means you have to connect your device to the computer using the USB to get it started once you switch it off .
Below is the screenshot of the tweet which was later deleted . Here is what he wrote [according to gadget blog Redmondpie] :

scotty6kids78: @MuscleNerd are we any closer to the untethered #jailbreak for the new #ios4.2 on #iphone4 ?
MuscleNerd: @scotty6kids78 it’ll be here by Xmas (not because we’re sitting waiting for Xmas, but because it’s achievable deadline)

Will this jailbreak be ultimate? As in that you don’t have jailbreak it anymore. They’ve been feeding us this and it’s been a while since I last heard of it. I recall they said that because of Geohot’s jailbreak release combined with the new update, they were gonna wait until 4.2 and 4.2.1 is here so WTF? Will this greenp0ison version be it?
What a useless update… we have known for ages its coming before christmas!!! just get the hell on with it!
Luis why to be so harsh? can you do it yourself? then , please be patient and thanksfull for the people able to do it…
Me I can not, period…and beside, you can still use your Iphone, no?
RELAX
Ya dude chill. You have been able to use your phone for te entire time before, I think u can go another week
I dont get it. Can I unlock iPhone 4 with bb 02.10.04 with this unlock then??
I don’t quite get it either. I stayed on 4.1 to have higher chances of an unlock and now there is all this talk about 4.2 being unlocked. My baseband is 02.10.04 – when will I be able to unlock this?
This is not unlock.
Its untetherea jailbreak for 4.2 ios.
The unlock isnt launched yet and no updates for that.
Great Job Guys!
So I’m hoping for a unlock soon also I have 03.10.01 Base band Version .
I am not 100% on this as I am new to this, but I did hear that if you have 03.10.01 you can never unlock it.
sorry.
(and if anyone knows more than me, and knows that I am wrong please dont hunt me down, I am only trying to spread the info that I have been researching)

Shaun,
The untethered jailbreak for 4.2.1 is already released, I don’t seem to find it. Could you point me in the right direction? Thanks
So pi**ed of with this unlock thing! I have been waiting for an unlock for over 2 months ever since I bought my Iphone 4.
When I got my phone it was running on 4.02 and by accident I updated to 4.1 with 02.10.04 bb! Since was this my first ever Iphone I thought that it will be unlocked easy since I was taking my phone out of UK. When stared reading more about the unlock it was said at that time that the unlock will be out at the beginning of November when IOS 4.2 will be out. It was said that the unlock was already ready just waiting for apple to release the new IOS.
Ne new IOS came out but not the unlock. THen was the rumor that it will be out before the Christmas now we are being told that it will be less then a month. I just wander is that true?
Was this the case with previous unlocks. What was the longest that people waited for an unlock? So far for me has been 3 months. I find it so annoying and pi**ed of at the same time because I held of for 2 years to get an Iphone and now that I got it I’m pi**ed of that I regret it.
They always give an update and at the end they post a new update saying it’s been delayed as always. I mean what’s the point of posting all the updates for if you’re not going to be honest and serious about what you do? At the end you freaking disappoint everybody nation wide. Same old l*me excuses after another we need some new hacks and developer who can be serious and honest and plus up to date with their work. Not like a bunch of lying idi*ts.
If u so desperately need a phone that works with all Telcos, then get a factory unlocked set. I got one. If u wanna be a cheapo and get the locked set, then don’t blame others for not giving u the unlock. U signed on the deal to have a locked set… Live with it.. Anything else is a bonus.
They sale unlock iphone 4 in the US?? Where did you get one and how much?
