Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
Restart phone
If you are not jailbroken
Sherif Hashim discovered that you can activate your iPhone 4, iPhone 3GS or even iPhone 3G without the original carrier SIM card. You need a “phonebook sim card” or 02 simcard. You can buy these type of sim at radioshack, bestbuy or other mobile electronics store (for example here).
Once you get passed the Emergency Call screen, connect to Wifi, jailbreak using JailbreakMe.com and unlock using ultrasn0w. Once that is complete you should be passed activation and unlocked (able to use any sim). If you get a different simcard error, do the following final step:
Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
Restart phone
If you have itunes invalid response problem:
Connect to wifi and ssh to your phone (via winscp, putty, terminal, etc).
Navigate to your lockdown folder (/private/var/root/Library/).
Delete pair_records folder
Reconnect the cable and see that your invalid response problem is gone.
If you bought your iPhone 4 on ebay you will need the official sim (at&t) or a universal sim, like ones you can grab at bestbuy for $10 this will get you passed Emergency Screen.
There is a big a security hole in iPhone iOS. The device is insecure in a big and obvious way. You should be extremely careful of what sites you visit.
The FlateDecode vulnerability can be used when a PDF File is embedded within a Web page. Basically Safari tries to parse the PDF. And when it does it executes some code. Hackers can use this exploit to read and write iPhone data, get your contacts, sms, even delete something. So they can get all kinds to access your personal information stored on your iOS device.
Apple will fix it some day. Until then you need to take care of your iPhone security. There is a fix for that. It is available via Cydia for jailbroken devices. So you need to jailbreak in order to secure (funny isn’t it?).
Will Strafach has released the fix as a Cydia-based package called “PDF Loading Warner.” Simply download and install the package. Every time Mobile Safari attempts to download and parse a PDF you will get the following message:
Now you can control, where to accept PDF (as not all of them are made by hackers) and where to select cancel.
FaceTime feature gives users the possibility to make voice calls. Apple restricted this feature to Wi-Fi only. Today it became possible to use it over 3G!
Jay Freeman, better known as Saurik, the creator of Cydia, was interviewed by the home radio Make It Work. He speaks about the history and the future of the iPhone jailbreak.
Saurik describes the origins of Jailbreak and Unlock for the very first model of the iPhone. Jay explains that initially there were two important things to do with the iPhone 2G -- to use other carrier than AT&T and to install any application.
He continues discussing the main applications from Cydia. Cycorder was the first to allow video recording, and Winterboard was the only one that allowed users to change the graphical interface of the iPhone. He also speaks about Comex, the hacker who is currently working with the Dev Team for releasing and Unlock for the iPhone 4. According to Saurik the tool is still not ready to be released to the public due to severe bugs in the code. Here the second part:
Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you’re at 4.0.1). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.
Install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com) if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).
DevTeam updated iOS 4 jailbreak utility redsn0w to version 0.9.5b5-5. That should fix any APN or MMS issues that users were seeing. It’s safe to re-run it on an already jailbroken iPhone without restoring. Just deselect “Install Cydia” if you do that.
Supported devices are still only iPhone3G and iPod Touch 2G (not MC)
Good news from DevTeam. They just announced via twitter that unlock for firmwares 3.1.3 and 4.0 is ready:
RT @MuscleNerd: ultrasn0w tips: 1) Works for all basebands since 3.0 FW 2) Remember to disable 3G on T-Mobile USA
ultrasn0w 0.93 released! Cydia repo is repo666.ultrasn0w.com. Works with basebands 04.26.08 thru 05.13.04
This means, that all users with basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04 can use ultrasn0w 0.93.
There is no jailbreak for just released iOS4, so you need to wait a bit. Firmware 3.1.3 who need unlock can update ultrasn0w and use their iPhones with any carrier.
Last week Apple has released its iPhone Os 4.0 beta 4 and redsn0w is finally updated to support this as well as beta 1. New version of jailbreak is 0.9.5.b4 and it can be applied on iPhone 3G only(!).
Redsn0w 0.9.5.b4 is targeted at developers who make jailbroken apps, and will not work if you are already using blacksn0w, ultrasn0w or yellowsn0w.
iPhone Dev-Team warns:
“You should stay clear of this beta software if you rely on a carrier unlock.”
To use the jailbreak, follow the guide below:
Download redsn0w 0.9.5.b4 here. (Only Mac OS X version since app are developed on this OS).
Make sure you have already activated your iPhone 3G with iTunes and your own developer ID.
Launch the jailbreak.
Select your stock iPhone1,2_4.0_8A274b_Restore.ipsw (beta4) or iPhone1,2_4.0_8A230m_Restore.ipsw (beta1) file that you used to update your firmware.
Choose “Install Cydia” and then click “Next”. Use DFU mode to install the redsn0w.
When your iPhone 3G comes back up, you will notice Cydia has a blank white icon. It also has no sources so you should go to the Sources panel and add this repo: http://apt.saurik.com/cydia-3.7 (make sure you are connected to the Internet before). When Cydia restarts, you should see its real logo now, and the standard sources should be ready to use.
The first release of Spirit had a bug that accidently could delete all of your photos from the device that was jailbroken. If you have a backup which you made before jailbreaking your iPhone/iPod Touch/iPad, here is a quick guide how to recover deleted photos.
1. Open Cydia and search for “OpenSSH” and then install it. Reboot your device.
2. Download and then install iPhone Backup Extractor.
