“Is possible to recover if things go wrong?

Yes you can

Please note the step-by-step guide involves restoring your iPhone so you should be aware this would mean that all your personal data from your iPhone, including songs, videos, contacts, photos, calendar information, and any other data will be wiped out and your iPhone’s settings will be restored to their factory settings. However, you always have the option to recover your personal data from the backup.

Here is the step-by-step guide to restore your jailbroken iPhone:

1. Connect your iPhone to your Mac or PC and select your iPhone from the list of devices in iTunes. If things had gone horribly wrong while hacking your iPhone and iTunes does not detect your iPhone then you will need to put it in DFU (Device Firmware Upgrade) mode.

2. You can follow these steps to put your iPhone in DFU mode

(this is required only if iTunes does not recognize your iPhone)

Connect your iPhone to your computer.

3. Turn iPhone off.

4. Hold power and home together for 10 seconds (exactly).

Release power but keep holding home until the computers beeps

(observed on a PC) as a USB device is recognized. A few seconds later iTunes should detect your iPhone. In the Summary Tab, click on the Restore button.

iTunes should prompt you if you would wish to take a backup of your iPhone before restoring. Select Backup.

After the backup is taken select the Restore option when iTunes prompts you.

Once the restore process has completed your iPhone will restart and the Apple logo will appear while booting up.

After the restore is complete and your iPhone restarts you will see the “Connect to Activate” screen. You must continue to keep your iPhone connected to complete activation.

The last step is to set up your iPhone either from a backup or set up as a “new iPhone”. Setup your iPhone as a “new iPhone” or you can select the date of your backup that you want to restore from. You can always follow the above procedure to restore from a backup at a later date also.

Step One
Press the Cydia icon on your Springboard

Step Two
Press to select the Sections tab at the bottom of the screen.

Step Three
Press to select Networking from the list of Sections.

Step Four
Press to select OpenSSH from the list of Packages.

Step Five
Press the Install button at the top right of the screen.

Step Six
Press the Confirm button at the top right of the screen.

Step Seven
Once installation has completed successfully press the large Return to Cydia button.

Step Eight
Hit the home button on your iPhone to return to the Springboard.

Step Nine
We must now obtain the IP Address of the iPhone. To do this press the Settings button on your Springboard.

Step Ten
Press to select Wi-Fi from the Settings Menu

Step Eleven
Make sure you are connected to a wireless network then press the circular blue arrow button.

Step Twelve
Take note of your IP address from the Wi-Fi details screen

Step Thirteen
Make sure you are on the same wireless network as your iPhone and launch WinSCP by clicking it on your desktop, or in the start menu. You can download WinSCP from here.

Step Fourteen
Once WinSCP opens, enter your iPhone’s IP Address into the Host Name Field. Then enter root as your iPhone username and and alpine as the password. Then click Login.

Step Fifteen
You will now see WinSCP connecting to your iPhone. The first time you login using SSH, it may take 30-45 seconds.

Step Sixteen
If a Warning dialogue pops up, click Update or Add

Step Seventeen
After about 30-45 seconds, WinSCP should successfully log you into your iPhone. You will be placed in the /private/var/root directory.

Step Eighteen
To get to the root folder of the iPhone you can select / from the dropdown on the right side of the window. From here you can access all the folders on your iPhone for example the Applications folder

Step Nineteen
To transfer a file to the iPhone simply locate your local (on your computer) file using the left pane. Then navigate to the desired location in the right pane. Drag the file from the left pane to the right pane to copy the file to your iPhone.

**Note**
As user dlr stated, it is a good idea to set auto-lock to never. You can do this by going to Settings>>>General>>>Auto-Lock and set to never.

Now that all the legal stuff is taken care of here is the write-up:

If your phone isnt already jailbroken its going to need to be for this to work.

once you have that finished (should take about 10 minutes or so) open up the “cydia” app.

*hit manage tab
*hit sources
*hit edit button in top right
*hit add button in top left

when box comes up add this link:
http://cydia.hackulo.us

*hit add source
once it adds the repository
*hit done in top right
*click the Hackulo.us section in added by user.

you must install in this order:
1: miPatch Firmware 2.2.1
OS 3.0 needs AppSync instead of miPatch!
2: Hackulous Security
3: Installous

once you’ve finished downloading those close cydia app, locate “Installous” app (green button with a 2g iphone icon).

*browse
*click on an app you like
*scroll down to bottom and find download section
*go to the iphone friendly section
*whenever you get to where the download is starting go ahead and hit install rather than download (saves you time)

when your viewing apps it will say they cost money but that is just the App store description they DO NOT cost anything and are the full versions of the app. ***SCROLL DOWN TO BOTTOM***

once its done with the install of the app you can either continue to browse around (there is no limit to how many you can download) or exit out of the “installous” app and try out your new app.

HERE ARE PICS OF THE PROCESS, IF YOU GET CONFUSED OR JUST NEED SOME REASSURANCE ON WHAT TO DO.
