These are instructions on how to jailbreak and unlock your iPhone 3G on iOS 4.2.1 using PwnageTool 4.1.3 for Mac OS X. This tutorial will explain how to upgrade your baseband if needed for an unlock.
Step One
Make a folder called “Pwnage” on the desktop. Download a couple of things:
If you are on the 05.14 or 05.15 baseband you will also need the iPad 3.2.2 firmware. You can find out your baseband version in Settings -> General -> About -> Modem Firmware.
These are instructions on how to jailbreak your iPhone using PwnageTool 4.1 for Mac OS X. If you need unlock and you have not updated to iOS 4 you will be able to preserve baseband and unlock iPhone using ultrasn0w.
This guide will work for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 4G, iPad and AppleTV. Just use the right firmware and select the right device (step four).
Step One
Make a folder called “Pwnage” on the desktop. Now you need to download there PwnageTool 4.1 from here and iOS 4.1 firmware from here.
When downloading the IPSW file, it is best to download it with Firefox since Safari often auto extracts it!
Step Two
Double click to mount PwnageTool then drag the PwnageTool icon into the Pwnage folder.
Today Apple released patches for its iOS that address a security hole in Mobile Safari, which allowed users to jailbreak their iDevices. The PDF exploit they used also allowed hackers to gain remote control over the device with an iOS.
You can update your device via the links above or simply by connecting your device to iTunes and clicking Update. But note, if you want to continue using jailbreak you should not update your handset/tablet and don’t forget to backup your SHSH blobs.
Now adding Flash to your iPhone and iPad is very easy. Apple didn’t want Flash to be on their devices. Several hackers created a project Frash – a Flash port for iPhone and iPad. Today it is available as a package in Cydia. To install follow these steps:
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.
For those who can legitimately activate to the iPhone3G 4.0GM seed, the “point to previous IPSW” redsn0w trick works and will jailbreak your 4.0GM. The “trick” is to point redsn0w at the 4.0beta4 IPSW instead of 4.0GM (do this after you’ve updated to 4.0GM and activated through the new iTunes 9.2 on your Mac). Since the carrier unlocks aren’t yet supported at 4.0, don’t do this if you use yellowsn0w/ultrasn0w/blacksn0w. Many JB apps are still pretty buggy in 4.0, so again this is mostly useful only for developers of those JB apps.
Note: If you’re experiencing MobileSafari crashes, double check that you’re running the version at the bottom of this page.
For those without legit iPhone3G 4.0GM seed access, please wait until the full public 4.0 release for updates to the jailbreak tools.
Geohot, the famous iPhone hacker and the creator of different jailbreak and unlock utilities (purplera1n, blackra1n and blacksn0w), is now working on a new jailbreak utility. It will support untethered jailbreak for all devices with the latest bootrom and the latest firmware. This includes iPhone 3GS and iPod Touch 3G.
Here is what Geohot writes in his blog:
The jailbreak is all software based, and is as simple to use as blackra1n. It is completely untethered, works on all current tethered models(ipt2, 3gs, ipt3), and will probably work on iPad too.
Don’t ask about a release date. You won’t make it happen any sooner.
It is still unclear if he used one of the recent iPhone Safari hacks to gain control of the device or if this is something else.
Recently MuscleNerd, the member of DevTeam, reported the presence of an interesting security bug in Safari for the iPhone. It will probably allow a quick remote jailbreak of iPhone or iPod Touch simply by connecting the device to an external website created for this purpose.
The bug was discovered by two hackers Ralph Phillip and Vincenzo Iozzo, who won the prize of $15 000 during CanSecWest. Their initial idea was to use a web portal to do the exploit of the SMS database and retrieve it’s content.
