ipod model mc544ll. version 4.3.3. Will no longer connect to face time or upload pictures

terryconnors, Welcome to the Apple Supprt Communities!

To continue using FaceTime, you must update to iOS 6.1.6 since device certificate is expired.

(especially uploading photos for email)

And you can't use older version at all times.

(For me, I use newer version at all times)

To update connect the iPod to yor computer and update via iTunes

iOS 4: Updating your device to iOS 5 or later

You need iTunes 10.7 or later on the computer
