What to do.

Step 1: Find your ipa.

An ipa is the file extension of your app before it gets installed to your idevice. You will need to find it on your computer if you sync with iTunes, or you will need to use appcrackr to rebuild it. On pc your ipas should be in C:\Documents and Settings\YOUR USER NAME \My Documents\My Music\iTunes\iTunes Media\Mobile Applications. If you rebuild the ipa via appcrackr you will need to browse for your ipa in your idevice file system, they will be in /var/mobile/Documents/Cracked.

Step 2: Copy your ipa to your desktop.

You will need to copy the ipa from the iTunes folder or your idevice onto the desktop to edit.

Step 3: Change the file extension of the ipa.

You will need to rename the file extension of the app from .ipa to .zip so that you can browse the contents of the app. After you rename it to .zip open it and open Payload>AppName.app and browse for the info plist. Copy the file to your desktop and open it with plist editor for windows.

Step 4: Edit the strings

You will need to search the plist for these two lines.

Controls the name of the app.

CFBundleDisplayName
iKnights

Controls the address of the app.

CFBundleIdentifier
com.addmired.idragonfree

You need to match the com.addmired.idragonfree string to the name of the AppName.app folder, in this case iKnights.app, so you will change it to com.addmired.iknights01 and rename the iKnights.app to iKnights01.app. you can repeat this as many times as you want like iKnights02, 03, 04 etc. Just remember the last part of the address must match the AppName.app folder. As for the name of the app you can change the string to whatever you wish iKnights test, and that is all u need to edit.

Step 5: Installing or Transferring ipa into your device.

After you edit the info plist and save, you need to put it back into the zip file Payload>AppName.app and replace the one inside. Then you can rename the file back to the ipa extension (iKnights.ipa etc.) Once that is done all you have left to do to drag and drop into iTunes or use winscp/ifunbox to copy the ipa file into /var/mobile/Documents/Installous/Downloads. Then either sync the app into your device or open Installous and install your edited ipa.

Congratulations! If you followed the instructions above correctly you should have a duplicate app on your idevice. Enjoy!
