The popular tweak FolderCloser has been updated to support iOS 4.1 FolderCloser is an install-and-forget plugin which closes Folders as soon as you launch your app. You’ll never have to manually close folders again when you switch back to SpringBoard. If you like FolderCloser, please consider supporting the dev by buing one of his awesome [...]

Annoyed of the shake-to-undo-function in iOS? Here is the solution: This little tweak lets you disable “shake to undo”. It comes with a SBSettings-Toggle; you can toggle within apps without having to restart them. Just install and enjoy! This will not add any icons to your homescreen. You can uninstall this to disable or toggle [...]

Late Friday the news was made official and quite large news it was; Cydia owns Rock

This will mean different things for different people, but we feel it is a great move for the jailbreak community

EDIT: YourTube 2.0 for the iPhone/iPod touch is now finally out as well! Straight from the crack team of tweakologists at Cocoanuts comes YourTube HD 1.2, with newly-minted support for importing downloads directly to your iPod library! Much like its smaller sibling, YourTube 2 (available soon!), YourTube HD will be able to seamlessly integrate your favourite [...]

Update #2: Finally got to the bottom of this, thanks to Saurik who clarified it for me. It seems that more shsh are on file and even some of you that havent ever jailbroken and just got a new iphone may actually have an shsh on file. It’s definitely worth a try to set up Saurik’s signature server in your hosts file and try to restore that way. You may get lucky and get a downgrade even on a new device.

————-

Update: It seems this method is very hit-and-miss. So far, only users with 3gs have claimed it works. Personally, I am still a bit skeptical. However, there is some compelling evidence to think that there is some level of success with this. Semaphore, author of Umbrella, has written a good post saying that this method is impossible. I also originally thought that, but there’s a point in Semaphore’s post that he does not address, and this very point is what made me write this blog entry last night.

Semaphore claims that the users must have had an SHSH on file. That when they used Saurik’s server, it responded with the SHSH on file and that’s why the restore works. When CodeBlue presented this method last night, I told him the same thing. But multiple users are presented with the “make my life easier” dialog in Cydia after doing this method. Make my life easier will never appear if you already have an SHSH on file for any firmware. What people don’t realize is that once you make an SHSH request in Cydia, it’s a one-time deal for life. You are requesting SHSH on file for every firmware starting with the current one being signed. It does not matter what firmware you are currently running.  If your restore worked because, as Sempahore’s post indicates, you had an SHSH on file already, then when you loaded Cydia, you would see the SHSH on file for xxxxxxx screen and you would never see the “make my life easier” screen.

All that being said, I have not personally tried this. I cannot confirm personally that it has worked. I have talked with several people that claim it has worked and many that saw “make my life easier”. At this point, either this method does work sometimes, Apple is accidentally signing 4.0.1 for 3gs intermittently, or the people claiming success are lying and did not see make my life easier.

End update.

A user named CodeBlue has discovered an unconfirmed method that may allow you to downgrade your 4.0.2 iPhone to 4.0.1, jailbreak, patch the safari exploit with Saurik’s patch and be jailbroken safely. This may be your only option if you have an out of the box iPhone with 4.0.2 on it and no other way to jailbreak. Note that I did not try these steps. They sound good to me in theory and others are reporting some success. After all, you have nothing to lose if you are already stuck on 4.0.2 without an SHSH in Cydia.  Here are the steps:

1. Download 4.0.1 ipsw

2. Extract it with winrar or winzip  to a folder on the desktop. You may need to rename the firmware file from .ipsw to .zip to do this.

3. Open the buildmanifest.plist with the notepad. Search and replace all – 8A306 with 8A400.  Save. Repeat the same with the file restore.plist

4. Download 4.0.2 ipsw and open this with winrar or winzip. Note: do not exact it. Just open it and leave it open. You must use this exact file and not create a new one. If you have to create a new one for reasons like you are on OSX, then use zip command line not explorer or finder to make the zip. I will assume you are using the original file opened in winrar for the rest of this guide.

5. Take all the files from the 4.0.1 and drag them over to the 4.0.2 zip archive that you have open.

6. Delete all the dmg files that have 002 at the end, leaving only the 001 files left.

7. Save the archive. And rename it back to .ipsw if you changed the name to get winrar/winzip to open it.

8. Optional: (this helps ensure you get an shsh file request for the future, but should not be necessary to just restore 4.0.1).  Add the 74.208.10.249 gs.apple.com line to the host file. If you need help with this step, read this.

9. Put the device into dfu, open iTunes and restore the firmware you changed.

Check out the original post or give thanks to CodeBlue at his blog.

Note: this only works due to the similarities in 4.0.2 to 4.0.1 and 4.0. This will not be a way to downgrade to 3.1.x and may not work in future firmware updates.

Action Menu adds additional actions to the cut/copy/paste menu on iOS3.x and, with the 1.1 update, now on iOS4.0, iPad and iPhone 4′s Retina Display. New plus pack actions include Locate, Find and Send to Pastie.

The latest release of Safari Download Manager, 1.5, brings SDM up-to-date with all modern iOS devices! SDM 1.5 works on all OS versions from 3.0 to 4.x, on all existing devices, including the iPad and iPhone 4! Possibly best of all, this upgrade is free to all existing users! This is a special moment for [...]

Update: Saurik has released “PDF Patch” which solves the problem on all jailbroken devices. No need to update to solve the PDF exploit. Further, Apple did not patch older devices. This means that in order to have a secure older device such as a 3g, *you must jailbreak*.

The iPhone Dev Team has released an update to Ultrasn0w that unlocks the iPhone 4. If you decide you need to unlock your baseband for use on an unsupported carrier, make sure you do not take firmware Apple updates (such as 4.1 when its released). You can install Ultrasn0w from Cydia. Ultrasn0w is in the dev team repository, which is a default repository in Cydia.

Edit: essential cydia updates fixed the facetime / MMS issues.

Comex has pulled it off again with a great jailbreak. The jailbreak, “Jailbreakme.com 2″ is now released and all devices can once again be jailbroken. This one is very easy to use. You don’t even need a guide. Here are the steps:

1) Load safari on your iphone
2) Type in http://jailbreakme.com
3) Slide to jailbreak
4) Wait and soon you have Cydia.

Just like spirit 1, this is a user-mode jailbreak which requires you to be able to load safari on the device.

I strongly urge you all to visit comex’s site and donate to him to help motivate him to find further jailbreaks in the future.

Those of you having problems where the device sits at the purple screen forever may benefit from clearing your cookies and restarting safari:

1) Put your device into Airplane mode.
2) Go to -> Setting -> safari -> Cookies -> Accept.
3) Double Tap home button.
4) Press and hold an icon to wiggle the task switcher icons and then quit Safari using the X.
5) Clear all Cache and cookies.
6) Open safari and go to jailbreakme.com and try again.

Since the jailbreak is due very soon, I have created SpringFlash, the first iPhone 4 only Cydia app. SpringFlash is a springboard activator based LED flashlight for your iPhone 4. In short, you can have a touch of a button for a bright LED flashlight without hassling with unlocking your iPhone, closing your app, or even turning on your screen.

To use this, jailbreak, install it, go to settings app, activator pane, pick the activation method of your choice, and select the Flashlight. I am using short hold power, myself. It works very well.

Like all apps I write, this is free to jailbreakers in Cydia.

It looks like an exception has been added to the DMCA for jailbreaking and installing 3rd party “non-vendor approved” applications on a device like the iPhone. While this is something the community has always deemed as legal, it is now officially called out in a law as legal. More at the Washington Post story.

While I’m no lawyer, I would argue that jailbreaking has always been legal. In short, there was no law that said you could not jailbreak. Laws are drafted as such that they call out only what you cannot do or what you must do. Everything in between is considered legal. For example, there’s no law that says you may go to the store on Tuesdays, and no one is questioning whether or not that’s legal.

Still, it’s nice to be called out as legal.

Modmyi has written a great article on this subject and I encourage everyone to read it.

Attention all jailbreakers (hopefully this is everyone).

Comex has announced that he’s not waiting for 4.1 for his next jailbreak. So make sure you save your SHSH for 4.0.1 in Cydia or using firmware umbrella. Note also that as of 4.0, 3g devices also verify with apple before restoring. While there are other ways around a downgrade for 3g devices, you should also save your SHSH’s to be safe.

If you want to save your SHSH using firmware umbrella, grab it here.

If you want to use Cydia, even if you haven’t jailbroken yet, you can alternatively restore your device using saurik’s server (instructions here) and this will automatically put in an immediate SHSH request.

The firmware umbrella method is probably your easiest method and the one I recommend. Make sure you set it to Cydia on the advanced settings page so that you get it into Cydia this way. Whether or not you save the local file is up to you. (Probably a good idea, but I dont bother).
