After doing some research I’ve written a guide for converting your iphone .apps to .ipas on a Mac. This will enable the app to be brought into itunes and synced like and appstore app (if you have a cracked mobileinstallation file). I’ll be converting macman into an IPA:
1. First you are going to need to get the .app onto your computer. I downloaded macman with cydia and then copied it on to my computer using cyberduck. Guides for copying things to your computer from your iphone, or ipod touch, can be found on you tube.
2. Control-click the .app and select show package contents. Find Info.plist and you are going to need to edit it with text edit.
“You can read a binary plist file in a text editor by converting it to XML format. Use the following command in Terminal:
plutil -convert xml1 /path/to/file.plist”
For example: plutil –convert xml1 /Users/Johndoe/Desktop/Macman.app
3. Next you are going to need to add a few lines to the Info.plist. Locate the line:
<key>UIPrerenderedIcon</key>
<true/>
</dict>
</plist>
In between <true/> and </dict> your going to need to put:
<key>SignerIdentity</key>
<string>Apple iPhone OS Application Signing</string>
It should end up looking like this:
<key>UIPrerenderedIcon</key>
<true/>
<key>SignerIdentity</key>
<string>Apple iPhone OS Application Signing</string>
</dict>
</plist>
4.Once this is done, save the Info.plist where you found it
5.Now that the app is signed you are going to have to put it in the IPA “format”. You can download my cycorder .ipa here:

Change the folder name to the name of the application. Drop the .app into the payload folder and delete cycorder.app. If you don’t care about itunes artwork delete the itunes artwork file. I havn’t figured out how to get the icon to display as the itunesartwork, but if anybody knows feel free to write something in the guest book.
