You are welcome.

If the apps that need updating are Apple apps that came with the phone, try going to the App Store Purchases tab or click on your profile and then go to Purchases to see if there is an option to accept the applications with your Apple ID. If that doesn't work, you can delete the apps and download them with your Apple ID. The apps are free. You may have to sign out of the App Store, restart the devicer, and sign back in to download new copies.
