Before you do anything to your iPhone, do note that in jail-breaking your phone might not be breaking the law, however using software that are copyright are the same as illegal downloading of music that is against the law.

Hacker @pod2g came out with untethered jailbreak for iPhone a while ago and finally last night (local sg time) redsn0w is released with unthethered jailbreak that works for iOS5.0.1

Also do note that this jailbreak is only for iPhone 4, 3GS, iPod Touch 4G iPad and not valid for iPhone4S (the lastest iPhone) or iPad2.

The links I will be using are links from http://www.limera1n.cc/2011/12/jailbreak-501-untethered-iphone-4-3gs.html

You can see the tutorial there. Basically I am just describing my experience and sharing things you should know about jailbreaking your phone.

So first step, is your iPhone a Jail-broken iPhone of a original iPhone that was not jail-broken before? Which ever it might be, this are the steps I did for my iPhone.

If you are unclear of anything, please do not attempt to do anything, please clarify your doubts. Do it at your own risk! I am not responsible if it fails :)

Step 1: Backup your Data 

The last thing you want is to have a Jailbroken iPhone with nothing in your phone. All contacts gone. Like a brand new phone. Updates are important and I recommend not just performing backup when you wants to do something to your phone. You should do regular backup of your phone just in case something goes wrong with your iPhone and you will have backup data stored in your PC.

So Basically how do you do it ?

Firstly, download the latest itunes from apple website. http://www.apple.com/itunes/ For now, we are using version 10.5

I would recommend you to copy all your photos into your hard drive using windows explorer to make sure you don’t lose all the precious memories.

For me, I connected my iPhone to iTunes via USB and wait for iTune to discover my phone. Please note I have auto-sync turned off. In any case your iPhone is having auto sync, perform a swipe on the iPhone to interrupt the syncing right after you connect can save you from having unnecessary trouble if you don’t want your phone to sync.

Next for Jailbreakers who had unauthorised app on your phone installed, if you don’t want to lose them , perform a transfer of those apps into your iTunes. On the left  perform a right click on your device and you should see a pop down menu, select transfer purchases. You should have iTunes transferring all the apps from your iPhone onto iTunes.

After you have successfully transfer purchases it’s time to do a backup of your phone. Right click on your device again and select Back Up. A copy of your iPhone is being backup .

So you have right now get your iPhone ready for jailbreak.

Step 2 : Getting the programs.  

You need the following programs:

- an iTune version 10.5 which we have downloaded in step 1

- ipsw version 5.0.1 (this is the firmware of iPhone iOS5.0.1) – Download link

- redsn0w version 0.9.10b1 – Download Link 

If your phone is not on iOS 5.0.1 yet, if it is, you can skip this step.

You can either, update it using iTunes automatically via iTunes, or restore your phone with an ipsw file.

Download firmware 5.0.1 for your iphone at the following link.

http://www.limera1n.cc/2011/11/ios-501-ipsw-download-for-iphone-ipad.html (link source belongs to limera1n.cc)

Save the ipsw file to a location and remember where you save it.

Step 3: Restore your phone to iOS5.0.1 (Skip this step if you are already on iOS5.0.1) 

Hold onto your shift button on your keyboard and click on restore at the same time. This will allow you to select the ipsw file which you want to use. Please note that this step will set up your phone into a “new phone” where everything will be gone, your playlist will be gone too and require re-sync from your itunes later.

Select the ipsw file from the location you saved it in the step 2 , and let the iphone restore to iOS5 . It might take a while for your phone to do that.

After the phone is upgraded to iOS5, you are ready to jailbreak your phone.

Step 4 : Jailbreaking

Run redsn0w version 0.9.10b1 - Download Link  at the location where you save it. (Make sure you run redsn0w as administrator) For vista users, right click and select run as administrator.

You will be brought to a page in RedSn0W , select JailBreak

Next redsnow will prompt you to switch off your phone before click next, this is to enable you to go into DFU mode so that redsnow can do modification to your phone.

Follow the steps after clicking next to get your iphone into DFU mode while still connected to your PC.

The Steps are something like this, follow the instructions in redsnow. 

Hold power off button for 3 seconds, Apple Logo Appears.

Hold Home button without letting go of Power button for around 8 seconds, Apple Logo Disappears.

Release Power Button but keep on holding on to Home button until redsnow detects your phone is in DFU mode.

When the phone gets into DFU mode, redsn0w should start jailbreaking your phone, you will end up seeing redsnow telling you that the rest of the jailbreak will happen on your phone. It will take a while, be patient.

Install Cydia

There will be four check boxes, the first one is install cydia, make sure that box is checked and the rest unchecked. Press next.

It Screwed up!  

In any case that your iphone went into DFU mode (Black screen) and totally no respond to all buttons, don’t panic. Press and hold both power off and home button at the same time until you see an apple logo appear (exiting DFU Mode)

Retry the process.

In any case that your phone went into apple reboot mode which you cannot boot up your iphone which a fail jailbreak might result in your phone being a little crazy or suddenly you just went into the iTune Restore mode, where you get a usb cable pointing to the globe, restore the phone using iTunes again with step 3.

Step 5 Jailbroken! 

If everythings goes well, congrats! you have a jailbroken iphone4. So what now? I don’t have any contacts nor do I have any apps that I use to have with my jailbreak iOS4 phone?

THE FOLLOWING STEPS ARE JUST FOR YOUR INFORMATION, DOWNLOADING COPYRIGHT SOFTWARE AND USING IT IS AGAINST THE LAW. 

Look for cydia on your jailbroken iphone. Run it.

At the bottom of cydia you will see 5 icons (Cydia, Sections, Changes, Mange, Search)

Click on Manage and you should see Packages, Sources, Storage .

Click on Sources , on the top you can see Manage on the left and Edit on the right. Tap on Edit.

The top changes to Add and Done , Click on Add on the left and a window will pop up for you to enter Cydia/APT URL.

Enter the following “Http://cydia.hackulo.us” and click Add Source.

After which click on Done

Now at the bottom select Search , search for Installous and select installous 4. Next click on the top right that says Install

Proceed with the installation. If it happens that there are red words with black background poping up, double tap on your home button, end cydia and then run it again. Make sure all packages are updated before you try to search and install installous 4 again.

Once you are done, go under manage -> Packages and make sure you have  AppSync for iOS5+ installed.

This is to allow you to sync illegal apps from your itunes to your iphone (reminder: Using copyrighted apps are against the law)

After you are done, open your itunes again.

Step 6 - Get everything back. 

Now that you have get your jailbreak phone ready, connect your phone back. On the left, right click on your device (your iphone and click Restore from backup… select the backup that you have performed before the restoring the phone to iOS5 . All contacts should return. Next perform a sync and all the apps that are downloaded into your itunes should go back to your iphone. If not, click on your device (left click not right this time) and you would see a summary of your phone. On the top, there is a App tab , click on it and make sure you check the box that says (sync apps) check the apps that you want to sync and click apply. The checked apps should go back onto your phone.

Step 7 It’s Done. 

Now that you have an iPhone with iOS5 up and running with jailbroken. Congrats. However again, please note that using copyright software without license is illegal.
