Semi-untethered iOS 5 Jailbreak Available, iPhone 4S & iPad 2 Not Supported
iOS jailbreaking has been for a long time a favorite procedure for many iDevice users that wanted to further customize their iPhone, iPad or iPod touch by downloading apps and resources that were not allowed in the official Apple Store, but, since we’re talking about jailbreak features, also to download pirated copies of the existing apps.

And while Apple doesn’t support jailbreaking and warns customers that such procedures may lead to a breaking the devices’ warranty, millions of iDevices users do it. In fact the iPhone Dev Team has already jailbroken the last major iOS version, iOS 5, and both Mac and Windows users can use the latest Redsn0w version to jailbreak their devices, or at least some of them.
Unfortunately the iPhone 4S and iPad 2 running iOS 5 can’t be jailbroken at this time, since they’re new products with fresh new hardware that doesn’t offer the same exploitable wholes previous devices come with. But every other iDevice that support iOS 5 can be jailbroken, not that we’d recommend you go down that path.
One minor caveat with the current iOS 5 hacking solution is that it doesn’t offer an untetethered jailbreak. That means you’ll have to connect your handset with your Mac or PC every time you want to reboot it into a jailbroken mode, hence we’re looking at a tethered jailbreak tool.
While the iPhone Dev Team works on an update for Redsn0w that will support untethered jailbreaks, we have found a Cydia tweak for you that will let you enjoy a partially-untethered jailbreak for your iDevice of choice.
This jailbreak solution is called “SemiTether” and it’s available via Cydia on the BigBoss repository. In order to get it you will have to jailbreak your iOS 5 device the regular way. Once Cydia is available and you install the tweak, you will be able to reboot your iDevice ito a jailbreak state without connecting it to the computer. However there’s a downside to using it: you won’t have access to Safari, Mail, Cydia and any of the jailbreak apps on the device. This tweak will let you practically reboot the device, when absolutely necessary, even when away from the computer. Once you have access to the machine again you’ll be able to reboot the iDevice into a fully jailbroken state and enjoy all the apps on it, just like before.
Have you jailbroken your iOS 5 device yet?

New Report Details a 5-Inch iOS Device, Is It a Next-gen iPod touch, iPad or iPhone?

Hmm. I want to install iOS 5 on my wife’s iPhone, but still holding off because of possible jailbreaking issues.
IOS 5 totally not worth it… On iPad one brower is crash happy (11 times an hour or so). No gestures, nothing worth wasting your time frankly… Only the notifications are prettier…
So after I “semi-tether” my iphone.If it dies. Will I be able to make calls and text? (atleast until I reconnect it)I know some of the functions will be blocked (cydia,mail,safari) but will the rest of the normal phone functions be blocked as well?
You can always test it before leaving your computer to make sure phone features are still available with the semi-tether/untether. I’d say they should be otherwise they would have been mentioned.
There shouldn’t be any since you can roll back to previous iOS version. You should be extra careful though if an unlock is also required after jailbreaking.
well better Semi-Tethered and being able to make calls and text than having to be black screened.
I guess this is my next move.
thanks.
this should do until an untethered hack is created.
hopefully soon
thanks
Hm really? I love iOS 5 on the iPhone 4. Did you try a new install?
tethered or untethered jailbreaking is like having forbidden sex.
Ya, all it blocks are mail, cydia, safari, and some apple inc. apps like iBooks. Others then that your fine. Personally I just get sky fire and the google app and it’s normal just without cydia tweaks. In other words you can call and text.
IOS 5 sucks! it reboots itself every 10-20 minutes! Waste of time! It is 100% useless! Ios 3 is better!!
Now don’t take this like I’m hating on Dev team or anything but why the hell do they continue to waste their time with these other jailbreaks that are pointless? I have the new iPhone 4S, 64GB and I would love to see them finally pop out the jailbreak for that. I’m salavating at the chance to use “MyWi” and use Internet speeds up to 14.4 MBS with my laptop on the go. OR! Use “My3G” and stream HD videos thanks to the major increase of speed of the A5 process. Ugh. I just have to keep waiting and praying they’ll finally release the damn Jailbreak.
I want to get the jailbreak, however I haven’t had a iPhone since the first version. Now I have the iPhone 4 an I need it because of nosey girl. I’m confused about the reboot thing can someone explain? Please tjamks
You have to be patient and quit acting as if you deserve a jailbreak. i am 99.999% sure you don’t donate, I’m sure that would help the cause if people jail broke.. the A5 chip is what’s slowing everything down in the first place. be patient and wait. besides, there are more users on iDevices not iPhone 4S and iPad 2 (jailbroken on 4.3.3 btw…)
if people donated to jailbreak*
stop cheating and you wont have to worry about it.
i just looked up semitether in cydia and i couldnt find it… did they delete it?
wtf are you talking about?
Can rolling back your os be done i mean like ios 5 to the previous versions ?
