If you have downloaded and installed Xcode to your computer and you don't want to pay Apple the $100 to test your application on your device or to submit it to Cydia, you can create a certificate to fool Xcode into allowing you to fully build and test your application.

The following steps will describe how to create this certificate, deploy it into Xcode, and a few steps on how to submit your application to Cydia once you're done creating it.

These steps are the same on a Mac or a virtual machine to run OS X.

1. Watch this video and follow it's instructions:

2.Once you've finished creating your app, Ctrl+Click the application's name and click on Get Info.

3. Navigate to the Full Path of the application, this is the file you will be submitting.

4. Go to http://modmyi.com/devportal and fill out all the details. They will email you once your package is in Cydia.

However wher i type the command sudo sh lemon.sh i get a warning saying "improper use of the sudo command could lead to data loss or the deletion of important system files.Please double-check your typing when using sudo. Type "man sudo" for more information." it then displays the message "to proceed enter your password or type ctrl-c to abort" and it does not read any of my key strokes??how do i ficx this so that i can enter my password?

hi i think think that the line |mv gen_entitlements.txt gen_entitlements.py" is missing "/" after ".txt" anyway i typed all the above before trying to make an app and when i open xcode i do not have the option "iphone patched"??i need help asap!!thank you

A) The lemon.sh script tries to run this code:

echo Backing up SDKSettings.plist from iPhoneOS4.2.sdk ...
cd /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk

I used the link you provided and installed XCode4 but my folder path is :


(iPhoneOS4.3.sdk and not iPhoneOS4.2.sdk) so the script fails with an error. I changed it to reflect the correct path and re ran and it went thru OK.

B)In step 4 above the path shown
/Developer/Library/Xcode/Project Templates/
is not the same as I have. My path is :
/Developer/Library/Xcode/Templates/Project Templates/Mac/

I copied the "iPhone Patched" folder and contents into this Mac folder. However when I restart Xcode this folder does not show up.

How do I fix this?

Completed Instructions, no iPhone Patched option on xCode
