How to install .ipa applications on your iPhone

There has been talk about people being able to install these ipa applications on their iPhones. It is possible.
Basically what this allows you to do is try before you buy.

There are a few things to point out first:

1. The purpose of this guide is to allow you to test apps before you buy them
2. Proceed at your own risk

Adding these apps to your iPhone is fairly easy. There are a couple of things you need first before we get started.

1. A jailbroken iPhone
2. OpenSSH installed on your iPhone
3. Knowledge of using OpenSSH
4. The patched mobileinstallation file which can be downloaded Here.

Just to let you know, I did have problems with this and ended up having to restore my iPhone twice. The problem was that I installed the wrong mobileinstallation file. If you download the one from the link above, you will be fine.

Here is the video of the process:

How to get the ipa apps:

You can download your favorites applications in our site.
if you don't find your application
you can request Here your ipa application for free of course.

Here are the installation steps:

1. Access your iPhone’s directory via OpenSSH.

2. Navigate to the root directory - /...

3. Navigate to the directory - /System/Library/PrivateFrameworks/MobileInstallation.framework/

4. Backup the MobileInstallation file already in that folder

5. Upload the new MobileInstallion file that you previously downloaded

6. Set the permissions of this file to 775. (right click,go to info, or properties)

7. Navigate to the directory - /private/var/mobile/

8. Set the permissions of the Applications folder to 777 -do not check make recursive

9. Open the Applications folder and create a new folder in this directory called - Documents

10. Set the permission of this folder to 777 - check make recursive

11. Navigate to the top directory

12. Set the permissions of the folder /Applications to 777 - do not check make recursive

13. Open the Applications folder and create a new folder in this directory called - Documents

14. Set the permission of this folder to 777 - check make recursive

15. Close the program and reboot your iPhone

16. Once your iPhone reboots, open iTunes, drag your ipa files into the applications folder within iTunes

17. Sync your iPhone and your apps will be there and they should work

18. If they don’t open, download a free app from the app store, then re-sync the ipa’s.

There are other ways to do this but I find that Cydia and Installer sources go down quickly once they are known and they get major traffic as we saw with NES roms.
