Urgent action required for anyone that likes jailbreaking 4.3.1, 4.3.2, or 4.3.3 and wants to do so in the near future.

For those of you unaware of the Apple firmware update policy, you can only restore firmware version that Apple approves. When you restore in iTunes, it goes to Apple’s web site and verifies if you are eligible for this specific version. This was solved by Cydia storing your SHSH (the is it ok to restore this version request response from Apple). This has been ok for the last year.

For current 4.3.2 SHSH, use the latest tiny umbrella version (same instructions) (Windows) and (OSX).

Watch the firmwareumbrella website for a 4.3.3 capable version and use it when you can!

To do this, go to advanced, uncheck “request shsh from cydia” and uncheck “set hosts to cydia on exit”. Then restart umbrella, go to show all shsh’s and save them all. In the logs you should see 4.3.1 come down. This will allow you to restore 4.3.1 or 4.3.2 through umbrella’s tss server if you need to.

Cydia’s SHSH system will hopefully be back up soon. When it is, I will post about it on this site. (Note: your older shsh’s are still safely stored in Cydia and are not lost).

Alternative to this is to install iSHSHit from Cydia, back up your SHSH and then email it to yourself. From there you can copy it to tinu umbrella’s SHSH folder.

Changes:

v3.3.1
• Fix: statusbar date on 4.2.1 or newer devices.

v3.3
• Fix: Updated fix blanks button to hopefully not crash when more than one blank exists
• Fix: Hopefully fixed the more app crashing when one of the ads cannot load.
• Fix: When moving toggles order, added back the “save” button so user knows to press “save” to save changes.
• Fix: Lock screen buttons when you hit the power button on the lock screen. Removed lock and the title so it fits.
• Fix: Internal window ordering in main drop down window to help compatibility issue with folder enhancer.
• New: Added option to more app, system options, to delete the carrier name to give more space to statusbar for things like date and free memory.
• New: Included Max’s Serious SBSettings HD theme that adds a retina icons display theme to default sbsettings. Thanks to Max at maxthemes.com for this great theme!
• New: Added retina icons for the more app for retina displays. Thanks to 42395_skyline for these icons!
• New: Added support for springboard key that was used by makeitmine app. This means that installing SBSettings should actually fix makeitmine. (I did this because it’s needed for the delete carrier name option).
• Toggles: Removed phone toggle from default. It doesn’t work on 4.2.1 and newer devices. Use airplane instead. (Phone toggle is now installable via separate package in cydia for older devices).

Note: Everytime I release an update to SBSettings, my inbox is literally flooded with a whole bunch of “SBSettings bugs” that are not even remotely related to SBSettings. Sometimes it takes a long time to debug these issues and point out which app had the issues. If you are having problems, and it’s some wacky thing that is not in the change log above, you should consider removing mobile substrate and all the apps it wants to remove, rebooting, installing sbsettings in this state, and seeing if you can reproduce the issue. Then reinstall your apps one-by-one. I know it’s a pain, but this is basically what I’ll recommend you do when I sense that the issue cannot be SBSettings related.

As the subject says. Apple is pushing iOS 4.3.2 via iTunes. You cannot jailbreak it so do not update. You will gain nothing and lose everything you have installed on your jailbreak.  The official changes in the 4.3.2 update is “fixes some facetime issue and 3g connectivity issues on ipad”. Sigh.

Dev team has released an untethered 4.3.1 jailbreak in the form of redsn0w 0.9.6rc9 or newer or pwnagetool 4.3.1.  Credit goes to Stefan Esser (I0n1c) for finding this one.  (Let’s hope he’s a new player here to stay, if you can find out where to donate to him, go do so).

You can download redsn0w MAC or Windows and use our guide here if you have questions.  Read more about it at the dev team blog.

Warning for unlockers: WARNING WARNING — ultrasn0w users don’t update yet! We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w.

Note: this does not work on 4.3 currently. Only 4.3.1. Also does not support iPad 2.

If you have problems with redsn0w hanging uploading payload on Windows 7, try setting XP Compatibility Mode.

So today, Modmyi put up a post about 4.3.1 tethered jailbreak being out.  But there is a reason I did not post about this. In fact, it should all be avoided.

Tethered jailbreak means that when your device reboots, you will have a connect to itunes logo on your screen and have to rerun the jailbreak software to get out of this mode. There is a “real” 4.3 jailbreak on its way out soon. You should all wait for that.

Further, the 4.3.1 tethered jailbreak bundles are incomplete and do not provide updated kernel patches.  The pwnage bundle going around is not a one created by the dev team. The ih8snow products are put together with no new code. Instead, they only assemble new bundles using existing older jailbreak exploits. (This is also why I never recommend using these products). No testing has been done, developers have not updated any tweaks / extensions for 4.3.1, etc. The update is not critical by any means, simply avoid it for now.

As for “this must be better than nothing right?” No, it really isn’t. I believe since the sandboxing issue isn’t worked out that Safari will be broken after Cydia runs the first time. To test this, I decided to jailbreak with it but unfortunately for me, after the jailbreak completes, Cydia won’t even load.

Updated 3/9/2011.

iOS v4.3 is out. This is mainly to support ipad2.  It adds a couple small features such as SMS reminder on incoming SMS messages, personal hotspot, and iTunes home sharing. Nothing big.

As always, I give my standard warning not to update and wait for the jailbreak release. This time, I am giving some extra caution, however.

At time of this writing, there is no jailbreak out yet. In addition, none of the new features are worth trading away your jailbreak. The first jailbreaks are likely to be tethered. So make sure you wait for an official update of greenpoison or redsn0w before you update. I’ll definitely announce when these are ready.

In addition, with 4.3 comes apple’s implementation of address space layout randomization (ASLR). In short, this will mess up the way mobile substrate works. You will need a new mobile substrate in order to use your favorite tweaks such as winterboard, sbsettings, bitesms, folder enhancer, etc. So you should definitely avoid 4.3 until an “official” jailbreak is released for it.

So for all of you USA users, anyone tempted to switch to Verizon now that they have the iPhone 4, I say do not do it. I purchased a verizon iphone and did some speed tests here in Oregon. At least in my region, AT&T was 10-20 times faster than verizon consistently in 3g data transfer rates.

Here are some tests:

Then I repeated the test with AT&T on EDGE. That’s right. I disabled 3g and used EDGE. I left Verizon on 3g, since that is the only way their CDMA works:

It appears that Greenpois0n RC5 B4 supports Verizon iPhone. Enjoy :)
Some packages may be currently blocked for installation.

We now have a support channel on IRC:
#ios at irc.thebigboss.org, chat.thebigboss.org, or irc.conceited.net. If you don’t have an irc client, you can connect wtih this link.

If you want a native IRC client you can use mIRC for windows or Linkinus for OSX.

Chat etiquette:
1) Please pick a decent nick name don’t use mib_34234j
2) If you have questions or need help just ask the channel and wait around. People respond as they see the question sometimes 15-20 mins later.
3) DONT TYPE IN ALL CAPS (that’s considered yelling).
4) Don’t send private messages to people without permission first. Your question should probably be asked in public and may be relevant to other users’ problems.
5) It is perfectly fine to “idle” there which means connect, stay connected even when you aren’t there. Many of us do that.
6) Have fun!

It looks like posixninja beat Musclenerd to the punch. Green poison RC5 is out and provides an untethered jailbreak.  The exploit used is already known to be patched in the upcoming 4.3 firmware so it made sense to get it released as soon as possible. Currently only the OSX version is out but a Windows version is on its way out as well. You can it from http://www.greenpois0n.com/

Note: this version does not provide hacktivation.

And a note from Musclenerd:
For those having trouble getting Cydia via the GP Loader, just let redsn0w install it (don’t choose the Monte option)

For those having problems in osx v10.5.x try this: http://www.gadgetsdna.com/jailbreak-ios-4.2.1-with-greenpois0n-rc5_2-on-mac-os-x-leopard/8634

A few people have asked me my opinion on iPhone 4 on Verizon and how it will impact us, if I will switch to Verizon, etc. Interestingly enough, my opinion is exactly stated perfectly by cmdshift here.  It’s an interesting (and short) read.

As he suggests, I also wait for summer to see what is in store with iPhone 5.

Update: SBingner has a fix in testing for this problem. See his page here.

If you are experiencing battery drain after installing ultrasn0w on baseband 6.15, here is a note from sherif hashim on the issue:

On a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it’s the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.

The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.

So to resolve this, u either:

A) try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it’s possible, by any means, try to have an access to one and use it

B) if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done

C) there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner, which will resolve that issue for those having it, the details of which shouldn’t be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for you

sorry for the long post and thanks for your attention

Yesterday, the dev team released their carrier unlock for iPhone 3g and 3gs devices. Many of you were waiting for this and assumed it was another exploit that would bring in a new carrier unlock.

Interestingly enough, it’s actually not. It turns out the ipad baseband hardware is the same hardware in 3g and 3gs devices. But the baseband is a higher number 6.x. Therefore, it seems that we can take the ipad baseband and install it on iphones then use the same unlock in ultrasn0w from last time. Unfortunately, this doesn’t work on iphone 4′s. Therefore, the unlock is for all iphone 3g, 3gs, and ipads running 3.2.2 or lower. iPhone 4 users, there’s no unlock available here nor will it be likely that one will be coming anytime soon.

Keep in mind, if your device is a 3gs new bootrom that a 4.2.1 firmware jailbroken will be tethered so you should not update to 4.2.1 due to this. However, 3g owners and 3gs with old bootrom need not worry about tethered jailbreak and are free to update.

The unlock can be installed directly from redsn0w or from pwnage if you are planning to make a new pwnage bundle.

Dev team released redsn0w 0.9.6b4 to jailbreak iOS 4.2.1 devices. Before you jump on the “update” bandwagon, let me warn you (for those that have not been reading my current posts). You may have a tethered jailbreak. I recommend not updating for anyone that falls into this situation:

1) iPhone 3g devices – no problems
2) iPhone 3gs devices – if you have newer bootrom, your jailbreak will be tethered. If you have older bootrom, you will not have tethered jailbreak.
3) iPhone 4 – tethered.
4) iPod 3/4 – tethered.
5) iPod 2 – MC model tethered, older model not tethered.
6) iPad – tethered.

Again, tethered means that after you jailbreak, you will have to rerun redsn0w every time you reboot.

Also, current redsn0w seems to have an issue uploading the payload. It took me about 20 tries. Eventually it worked. If the progress bar stops moving while “uploading payload” at all, it failed. Reset the iPhone, close redsn0w, and repeat.

Thanks to Semaphore (creator of tiny umbrella) for this information:

It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainer. Do not update to 4.2.1 even to test it at this point.
