My iphone is talking about provisioning expiration?

I have a iphone 4 and i have no idea what this means when this box pops up and says "Provisioning Profile Expiration, The profile "informate" will expire in 3 days" Somebody, please tell me what this means?

Request a new certificate. You do this in the Keychain Access application, which you can find by going into your Mac's Applications and clicking on the Utilities folder.
Inside of the Keychain Access, you will see the certificates listed. The certificates needed for development will be named something like "iPhone Developer: [name]" and "iPhone Distribution: [name]". They will also have a red circle with an X in the middle designating that they have expired. You will want to delete the expired certificates otherwise you can run into problems code signing your applications.
After you have cleared out your expired certificates, you need to generate a file requesting a new one. Do this by going into Keychain Access -> Certificate Assistant -> Request a Certificate from a Certificate Authority.
Enter a valid email address, your name and choose "Saved to disk" from the options. Click continue to save the file.
Go to the Certificates section of the iOS Provisoning Portal to upload the file and receive a valid certificate. Once you've uploaded it, you will need to wait a few minutes and refresh the screen for it to be issued. Hold off on downloading the certificate for now.
Choose the Distribution tab in the Certificates section and go through the same process to make sure you have a certificate to distribute apps as well. Again, hold off on downloading the certificate for now.
