Redsn0w 0.8 (Mac OS X, Windows, Linux)

Alright, so I use 2 laptops (both WinXP/Mac OS X Hackint0sh) and a desktop (currently flailing to turn on), and I have jailbroken iPods and iPhones with both Mac and Win, and the one thing I have realized (after gathering images for this tutorial for Win) is that it is THE EXACT SAME USER INTERFACE FOR ALL OS VERSIONS.  So we are not going to bother telling you how to do the exact same thing for all OSes, I will step you through how to do it on Win, and you can adapt that to either of the other two systems (I haven’t really gotten a chance to look at Linux UI but from what I have heard it is the same).  Here is what you are going to need:

iPhone/iPod Touch 3.0 IPSW File

Redsn0w 0.8 which you can get here

Once both of these are downloaded, decompress, (Linux & OS X: Mount the disk image first) and open the file labeled redsn0w (.pkg for OS X, .exe for Win, I am not too sure on the Linux extension), and a window similar to the following will appear:

Initial Redsn0w View

Click Browse and navigate to the iPhone/iPod Touch IPSW file and select Ok.  You will need to be online for this step if memory serves.  Redsn0w will now check the firmware file and make sure that it is valid, this can take a moment.  Click Next and the program will then prepare the jailbreak data and so on.

Loading. . .

You will then be prompted with which of these you want to install.

Icy causes problems with Cydia

Click Next and make sure you follow it exactly, the following step will require that you are careful and pay CLOSE attention to the instructions on the page.

Pay Attention Now. . .

Plug your device in, turn it off, and read the next step at least three times before going any further.

PAY ATTENTION TO THIS STEP

Ok, here’s the deal, you will need to follow these steps down to the second:

-Hold the Power Button (button on top of the device) for 3 Seconds
-Click and hold the Home button for 10 Seconds WITHOUT RELEASING THE POWER BUTTON
-Now let go of the Power Button and hold the Home Button for 30 Seconds, usually redsn0w cuts this off after about 10 seconds

These steps will place the device in DFU mode, allowing the program to install the jailbreak data.  Redsn0w will now begin loading the neccesary data, and you will see the following:

Installing crack. . .

Your iPhone/iPod will also display an image of a hardrive that says it is loading the jailbreak data or something along those lines.  After redsn0w is done installing the crack, you will get a Finished Installing notification and be prompted to exit the program.  Your device will continue patching the device from the inside and then reboot itself.  If all went well, the Cydia logo will now appear on the homescreen of your device.

Open Cydia, you will get an alert that asks which packages you would like to have access to, something like: Normal User, Hacker, and Developer; select whichever one is most appropriate for what you plan on using it for, this can be changed later.

Cydia Home Screen

Cydia will respring your device and then you can open it again and your done!  Go forth and play around, peruse the Cydia Store, download some fun tools and enjoy.

Pwnage Tool 3.0.1

Next utility, this one is for OS X only, and can be downloaded here.  You will also need the appropriate firmware IPSW saved to your hard drive too.  This tool is surprisingly straight forward to use, it is UI intensive fortunately and needs little explanation, so I will guide you as necesary but you should be fine.

Mount.  Open. Run Pwnage Tool.

Select your device, the 3GS is unsupported if I am correct (let me know if I am mistaken). Also select "Expert" or "Simple" mode

The program will locate the appropriate IPSW on the hard drive

This is the customizeable stage of the program

Ok, quick interruption, General contains information regarding partition size, phone activation, baseband etc for iPhone users, Bootneuter lets you adjust baseband crack settings, Cydia packages contains a list of sources for repositories used by Cydia, Custom packages lets you select which packages (Cydia and Icy(avoid Icy the best you can, it won’t let you use Cydia apps a lot of the time)) you want to install, Custom logos lets you select the boot logo and restore screen for your device, you can select your own image as opposed to the pwnapple.  After you have set everything you want and don’t want, click Build and let the program do its thing, it will ask you for your system password, just input it and the program will continue.  It will then inform you that you have completed construction of a brand new “Custom” firmware for your device, you can either follow a guided process to install it or you can simply restore it via iTunes, lets do that.  Open iTunes.

Option-Click “Restore” in your device’s page and navigate to your custom firmware.  Select it and click Ok.  iTunes will now restore your iPhone/iPod with your personal firmware.  Once the device has reset, iTunes will recognize it again and allow you to activate it.  Once you get to the home screen, you will see Cydia (and Icy if you’re into that).  Your device is now jailbroken, congratulations.

That is all for now, look forward to some MobileSubstrate plugin tutorials soon hopefully.

To start with, you will need the iPhone SDK (Xcode), available here. Download the latest version, which is currently 3.0 for unregistered users, and 3.1 beta3 for certified developers (To become a certified developer, you have to enroll with the Apple Developer Connection’s iPhone program. I will cover some hurdles related to this in a later post).  After you have downloaded the SDK, mount the dmg file and install. (This part is fairly straight forward)

After you have installed the iPhone SDK, open Xcode and select File -> New Project.

Project Types

File Name

When you’re there, you will be prompted with an array of options and templates to choose from for both Mac OS X and iPhone OS.  You will see six different options, but for this particular example, we will only concern ourselves with “View-Based Application”.  Select View-based Application and click Choose. . ., name your project “Hello World”, and a new window will then open, containing your application template.

New Project in Xcode

Here, you’re going to see many different file references and directories.  I’ll quickly go over what’s important:

Classes – In here you will find your application delegate and root view controller, with appropriate headers.

Other Sources – This contains the .pch (project header) that imports UIKit and Foundation Frameworks, along with the main.m file.

Resources – As of now, this contains the XIB files (for Interface Builder), and the HelloWorld-Info.plist. XIBs are static files used to create UIViewControllers. The Info plist contains the core settings of your application like icon location, opening orientation, Bundle Names, Identifiers, etc. Much of this is used by Apple when releasing your application on App Store via iTunesConnect (much on this “fun” process later)

Frameworks – This contains references to dynamic frameworks, including UIKit, Foundation, and CoreGraphics, with many more available on your system from the SDK.  This is also where static frameworks are stored, these frameworks are compiled into your application vs being linked to a dynamic framework present on the device.

Products – This contains the executable .app that you get after compilation.

Everything else listed here is either organization, compiling information, or other components that we will worry about in the future.

For now, we are going to concern ourselves with the Classes section only.  We will be using an NSString to store text, a UILabel to display the string of text, and colored background.  So let us begin by editing the HelloWorldAppDelegate.m, insert the following line of code at the start of the applicationDidFinishLaunching: method:

[window setBackgroundColor:[UIColor blueColor]];

This will make the background of your application blue as opposed to the boring default white.  There is a host of preset colors in the UIColor API, along with methods that let you create your own by setting the RGB properties.

Now go to your HelloWorldViewController.m file and navigate to the loadView method and uncomment it.  This method will contain the code that loads your UILabel, NSString, and UIView.  Insert the following:

CGRect appFrame = [UIScreen mainScreen].applicationFrame;
UIView *view = [[UIView alloc] initWithFrame:appFrame];
self.view = view;

Okay, let me explain: appframe is essentially just a rectangle the size of your device screen (320px by 480px), which is used by view to set the frame it is built around.  view then becomes the layer that the rest of the ViewController uses to display other “subviews” (like UIImageView, UILabel, UIButton etc).  Now we are going to add our NSString (the object that will contain our text for the UILabel).  Below what we just added, type the following:

NSString *hello_text = [NSString stringWithFormat:@"Hello, World!"];

This line creates and initializes the object hello_text with the text that we will be using next.  Now type below this:

UILabel *hello_label = [[UILabel alloc] initWithFrame:CGRectMake(0,0,200,30)];
[hello_label setFont:[UIFont fontWithName:@"Arial" size:30]];
[hello_label setCenter:CGPointMake(160,100)];
[hello_label setText:hello_text];
[hello_label setTextColor:[UIColor redColor]];
[hello_label setBackgroundColor:[UIColor clearColor]];

Alright, there’s a lot here so lets break it down, starting with the first line.  This line basically allocates memory for hello_label and creates a CGRect for whatever we place inside of it.  Next, we set the UIFont properties for the label (for a list of available fonts, look at the end of the post) including the font itself (Arial) and the size (in px) of it (30).  After that, we position hello_label’s center point so that it won’t appear at the default (0,0), but instead at our own custom position (160,100) (this is 160 px from the left, and 100 px from the top; think cartesian plain, quadrant IV).  We then set the string that we want to display, in this case we are using the contents of hello_text, this is done by just using the setText: property.  After that, all we are doing is setting the color of the text and the background of the frame using UIColor again.  Notice something weird about the background color?  Instead of setting a visible color, we use a clearColor, which is essentially just transparency. All that is left to do now is add the UILabel to our view and we can call it a day.

[self.view addSubview:hello_label];

This takes the object that we defined, and adds it to the superview. Build & Go.

Output

That is about it for now, Download the Hello World application used in this tutorial here: HelloWorld
