How to port iPad apps to the iPhone/iPod Touch

First:
1. Download your app from iTunes
2. Go to the app itself and copy it to a folder on your desktop (you can right click the app to open it in windows explorer)
3.Now go to the folder you copied it to and change it's extension from .ipa to .zip. (DO NOT UNZIP YOUR APP)

Editing and Finishing
1. Open info.plist with an editor (yourapp.zip\Payload\yourapp.app) (if you'r using windows I used plist editor for windows by iPod robot You can download it here: http://www.softpedia.com/get/Programming/File-Editors/plist-Editor-for-Windows.shtml)
2.
Replace

Code:

	<key>CFBundleIdentifier</key>
	<string>com.creator.appname</string>

With this:

Code:

	<key>CFBundleIdentifier</key>
	<string>com.creator.appnameiPod</string>

3.
Replace

Code:

	<key>UIDeviceFamily</key>
	<array>
		<integer>2</integer>
	</array>

With this:

Code:

	<key>UIDeviceFamily</key>
	<array>
		<integer>1</integer>
	</array>

4. Now save this to your desktop (not the zipped folder)

5. Now go back to the root of your zipped app

6. open iTunesMetadata.plist

7.
Now Replace

Code:

	<key>softwareSupportedDeviceIds</key>
	<array>
		<integer>9</integer>
	</array>

With this

Code:

	<key>softwareSupportedDeviceIds</key>
	<array>
		<integer>1</integer>
	</array>

8.
Change

Code:

	<key>softwareVersionBundleId</key>
	<string>com.creator.appname</string>

To this

Code:

	<key>softwareVersionBundleId</key>
	<string>com.creator.appnameiPod</string>

9. Save this to your desktop

10. Now go to your desktop and open up the folder that contains your zipped app file. Drag the iTunesMetadata.plist into the root of the zipped uzu file and replace the old one. Now go to uzu 1.0.zip\Payload\uzu.app and drag the info.plist you made from your desktop into that folder and replace the new one (DO NOT UNZIP YOUR APP).

11. Now go back to the folder that you placed your app in and change the appname.zip to appname.ipa. You dont have to change the file name.

12. Open iTunes and drag the appname.ipa you just edited. It should now be under iPhone and iPod Touch apps

13. Now sync it to your iPhone and it should be on your home screen!

Maybe you should add a list of iPad apps that work and don't?

Very useful, Well done. Perhaps some screen shots and/or examples would be appreciated. Also maybe show us you using iPad apps on iPhone / iPod touch.
Thanks.

Ok i'll make some screenshot's. And you don't have to be jailbroken for most of these. Also I am going to put a list on there.

ABC Player doesn't work actually.
I'm going to try some free ones like TTRadiation and Harbor Master.

Ok i'll add it to the list.

WeatherBug - working

P.S. Could you send me some screenshot's of the iPad app on your iPod Touch. Right now I dont have access to my iPod Touch

let me reinstall it, it crashes my ipod though.
