A couple weeks ago I set out to try and figure out, how to install the same application twice on the iPhone. The results where slim to none and there was only one site I found that had promise, but every time I tried it the app would crash before it could fully load. So I decided to take the little information I had learned and figure it out on my own. And I am happy to say I had success and have had the same application on the iPhone working for a week with no issues.
Watch the video or follow the step by step directions and if you have any issue getting it to work just let me know what app and I will see what I can do.
Directions
- Open iTunes
- Go into the Application section
- Right click on the application you want to duplicate
- Select Show in Finder (Show in Explorer on PCs)
- Right click on the .ipa file and copy it to you desktop (or where every you’d like)
- Replace the .ipa with .zip – An IPA files is just another type of a .Zip file
- Un-compress the zip file
- Open the new folder and Go into the Payload folder
- Right click on the App and select show package contents (MAC ONLY STEP, Should just be a folder on the Windows)
- Find the Info.plist files and open it in you favorite editor. (I prefer Plist Editor Pro)
- Change the “Bundle display” name to whatever you’d like. This is the name that will be displayed on the iPhone (optional step)
- Change the “Bundle identifier” (I recommend just putting a 2 at the end.)
- Save the file
- Open your favorite FTP software and connect into your iPhone/iPod Touch
- Navigate to the root directory and then into the Application folder
- Transfer the application into this folder
- Reboot or Respiring your iPhone/iPod and the application should now be somewhere on your home-screen
- Open the App and enjoy
If you have any issue please watch the video above.
As most of you know I now have a Mac at work so I really don’t need to worry about this any more, but I gotta say I really wish I had this software back when I was messing with the Hackint0sh software installers. 
It seems like almost every carrier is doing a top 5 (some even 10) list. With these lists they allow you to add 5 to 10 “friends”and no matter what carrier/provider they use, you can call for free and not waste any of your minutes. They all seem to have their own little names. AT&T calls it the “A-List” and Verizon calls it “My Fave Five”. But in the end it’s all the same.
