I assume you mean uploading to networking sites. If so, that is odd that the function doesn't appear for you. It is all Sprint Picture Mail, so they should be the same.
1. Make sure you are opening the program from your programs folder entitled, "Configure Picture Mail"
2. Then choose, "Tap to Add"
3. Make sure the correct networking sites are checked
4. Choose continue
5. Go to a picture and click the softtouch "Menu"
6. Choose "send to your space"
If you can't find any other help try this app for uploading to
Facebook.
