Untethered iOS 4.2.1 jailbreak for iPhone, iPad may not happen in time for Christmas

About an hour ago, Comex fired out the tweet you see above, saying he might miss his self-imposed deadline for an untethered iOS 4.2.1 Jailbreak for iPhone or iPod touch by Christmas. For those of you not familiar with the current "state of the jailbreak", a lot of users (specifically iPhone 4 and newer basebands) are either stuck on 4.2.1 with a tethered jailbreak or are waiting to upgrade from 4.1 until there's an untethered option. For most newer models, firmwares, and basebands, redsn0w is the only option and you'll be tethered (which you may or may not consider a hassle). Supposedly, a newer version will allow an easy untether process via redsn0w. Looks like we could be waiting a bit longer than expected, unless another 4.2.1 untethered solution comes along sooner.

It's still unclear whether an untethered version is still going to require saved SHSH blobs. As Apple isn't signing 4.1 anymore, we'll hope for those users on stock 4.2.1 you won't need them.

If you were waiting patiently for an untethered solution before Christmas, you may be out of luck. According to Comex, that deadline may not be achievable. Are any of you anxiously awaiting an untethered Christmas present? Are you currently on 4.2.1 stock/tethered or are you still running 4.1? Sound off in the comments with your thoughts!

Untethered iOS 4.2.1 jailbreak for iPhone, iPad may not happen in time for Christmas


Yep.. I retweeted him immediately and even asked him to say it wasnt so. I am stuck on a 4.2.1 tethered because I forgot to save my 4.1 and older shsh blobs. So I can't even go back. :(

I'm just wondering if this has anything to do with the leaked exploit of SHAtter (or "supposed leaked exploit"). I'm still unclear as to whether it was "actually" leaked or it's a fake. Sigh, only time will tell.
I'm currently on 4.1 so I'm not as impatient as those that are tethered but airplay sure would be nice...

Yeah Ally. I really wish I could go back to 4.1. Air play and find my iPhone aren't that great. ;) plus some of my apps still aren't 4.2.1 compatible. So lame.

crap.. I had my JB iPhone replaced as it wouldn't turn on and I couldn't JB the replacement. I've been stuck on 4.2.1 patiently waiting for the release. I'm considering the tether JB option right now, hoping I don't need a reboot away from home.

I'm stuck unjailbroken on stock 4.2.1. I wasn't planning on jailbreaking my iPhone 4, but changed my mind a couple of days after I updated to the latest firmware. Damnit!

Thanks Comex - I appreciate what you do for us and will look forward to the untethered break.

I respect and appreciate the tweet from @comex. These genius developers, all of them, make a wonderful contribution to the iOS community.
I can't wait until the untethered jailbreak and unlock is ready. More importantly I know they are doing everything the can do. Most of the iOS community feels the same way. It's important to remember the people like me who are appreciative rarely post because it shows what a minority the complaining posters truly are. These posts need be disregarded due to the immature and socially inept nature.
Thanks for all the hard work on the 4.2 jailbreak! It's greatly appreciated. I'm sure it will be here soon enough.

Hehe, I'm tethered on my iPod Touch 4G and (within the hour) my iPad. Seeing as I never really need to reboot either one, I'm perfectly content to stay tethered. I don't have an iPhone so yeah...

Doesn't matter to me, I have a 3GS early bootrom on 4.2.1, although I also have a 4 i'd like to get unlocked.

i'm on 4.2.1 and waiting for it. but i knew it was to good to be true. now i know it's xmas and all and they should be spending time with there loved ones but, why get our hopes up then right at the last second pull the rug out from under our feet.
buuuuuuuut and this is a huge but. maybe he said that so people would stop bugging him about it so he said it so he could crack down and get it out to us.
but idk, i'm pissed if we don't see the jailbreak on or before xmas

Frick, man!
I got a new iPod touch 4G a couple weeks ago and immediately updated to the latest firmware (4.2.1), expecting there to already be a jailbreak for it. There wasn't, so every day I've been checking the progress of the untethered jailbreak and was even hoping it would arrive BEFORE Christmas even though they said the release was by Christmas.
I need the jailbreak! Without it, my iPod feels like it's been in "DEMO" mode for all these weeks...I mean, it's a FANTASTIC--and I mean FAN.TAS.TIC. device, but without jailbreak, it just doesn't seem complete.
Thanks for the hard work, comex!
Thanks for keeping us updated, TiPB!

It seems there has been some drama between our two most esteemed developers. I'm sure that I'm not alone when I say that your loyal fans do not want you two to fight.
Thanks again for the hard work and hours you all put into providing a truly open device platform. We support both comex and musclenerd and anyone else who tirelessly works on iPhone JB.
There are a lot of us holding out for the untethered JB, and we know you guys can do it. Just think of the satisfaction you give yourselves and other JB users when we give AT&T the middle finger to their charges for tethering. Or the fact that Apple won't implement a decent utility to manage wireless features. . . But you guys make that all possible!
We salute you two and wish you a merry Christmas or happy holidays!
Also, merry Christmas/happy holidays to everyone else out there!

Huge thanks to all the people enabling jailbreaking and unlocking!! We are the beneficiaries of all their generous, hard work.
I'm happily jailbroken and unlocked with my iPhone 3G. (Kickin' it old school has it's perks I guess.)

"a lot of users (specifically iPhone 4 and newer basebands)" and "For most newer models, firmwares, and basebands" - you mean Bootroms. Baseband's got nothing to do with tethered/untethered Jailbreak. Baseband version is only relevant for unlocking purposes. ;)

Well I am very grateful that I even have a tethered jailbreak for 4.2.1 at least it's something until they finish. You guys and gals really need to stop and think about what you say. These people are working there ass off to finish a Jailbreak that they don't even have to share with some of you assholes. The least you can do is show some respect for there time and effort if it wasn't for them none of us would have a jailbreak at all.

I m a ipOd touch 4g owner & updated 2 4.2.1 immediately after purchasing it.I don't use web based apps much & checking for jb atleast twice a day.also 4.2.1sucks 2 me. The only thing I cud wish is a jb as a new year present.

My iPhone 4 is 4.2.1 JB Tethered and the only times I've had to reboot was when I needed to. No sudden crashes,,,,ever. @comex Take your time. I know when ya drop the new tools it will be well worth the wait!!

The only time itchy to re virginze my jb iPhone 4 running 4.0 is when i start see apps in the app store that require me to update rh OS. The new alomgplayer for iPhone requires 4.2..... Main reason I updated and loSt my jb..... Kinda tired of the cat and mouse game. If iPhone updates were OTA and did not cause you to lose your jailbreak. Life wouk be freat!

I'm a happy ipad user with the tethered jailbreak, but I keep a netbook in the car in case of reset. I can wait a bit longer and would also like to add my thanks to all the developers.

I'm still on 4.1, can't afford to lose MiWi as I use it for work. I'm patiently waiting for Comex, you can't rush perfection. He'll get it there eventually, and what's a couple of days when we're all screwing around with family anyway? Keep up the good work dude, we know you'll come through for us soon.

Crap, was hoping he was screwing with us... Been sitting at work all day, BTW we celibrate X-mas today so that kinda sucks..
Well, we just have to wait for Comex to release it..

shoot. BUT take it easy! It's christmas, and you deserve to have you holidays too. There's no need to make yourself work during holiday week on this.

This is crap. Jailbreaking is just not worth the hassle. I really see no advantage. I have been on the tethered jailbreak for a couple weeks now, and Cydia is OK, but certainly not worth going thru this at every new firmware. I'm restoring my iPhone today.

i just bought my iphone 4 and the software is already at 4.2.1 so i hope 4.2.1 jailbreak will be out soon or else its not convenient for me and the other users whose stuck at 4.2.1.

Stuck on stock 4.2.1 After restoring my iPod Touch.
Wondering why I restored? Well, I screwed around with the .string files in the Springboard.app file. Really messed up everything.
Lost my 4.1 Jailbreak... so sad. Hopefully this untethered jailbreak will come out soon.

stuck in 4.2.1 stock with my ipad. it's useless without jailbreak damnit. but thanks to @comexx. im just waiting :D

It's sad it is not out. However with all technical things sometimes it just happens. Thank you so much for all the time and effort you put into this! Whenever it comes out I am happy. I just got the iPhone 4 for Xmas and am waiting to jailbreak it, but I am patient and can wait. :)

I acidently restored and updated to 4.2.1 and now I lost my unlock and jailbreak . My phone is like a iPod now. Please help

I hope the untethered jailbreak for iPad iOS 4.2.1 comes out soon. It's inconvenient when you always need to boot to tethered thru redsnow when my iPad runs out its battery.
