Thanks for coming to the forums to report the issue you are having while uploading pictures to facebook from your device. I love being able to send pictures instantly to my facebook page so I can imagine your discontent.
Are you still having problems? We can tell if it is a network problem if you were having additional data problems. Therefore, are you able to access the browser? Can you access other web pages without issue? If so, then it may be an issue with facebook. What you can do is uninstall facebook by following these steps http://support.verizonwireless.com/clc/devices/knowledge_base.html?id=31369. Once it has been uninstalled, install it again and attempt to upload your pictures. Please follow up to let me know if that worked for you.
