I CANT SEND OUT MESSAGES TO FRIENDS... I DONT THINK THE CONTENT OF MY MESSAGES WERE VOLGURE AND WANT THE PROBLEM FIXED RIGHT AWAY

Your computer might have been compromised and has become a botnet. Run both Hitman Pro and Malwarebytes on your computer and see if it finds any infections.

Also, change your password on your yahoo email account right away.

it's definitely a problem of privacy...either yours (in this case going through your privacy settings will do) or your friends': although unlikely, they might have chosen not to allow people to contact them...

I think your phone memory may be too full, try deleting some content from your phone. I hope I have been of help but please do not hesitate to ask if you have any further questions.

reset your phone to factory settings. This will delet all the content of your phone so removed your memory card before resetting your phone.

new virus infection: it can be fixed through deleting extra key in registry settings. navigate to HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Internet Settings\ then delete keys other than 0,1,2,3,4. that extra key may be alphabet "I" or something.. (0-4 is IE default internet zone security setting..) get someone who knows around windows registry to set it right..goodluck

While your account is unconfirmed, you will not be able to send messages, write on your friends’ Walls, post in discussions, poke, tag your friends in photos or notes, comment on content, join groups, or fan Pages. This limit is in place due to security reasons.

my chat and message are not working on facebook account

i cant get into social chat

Maybe you never activated the phone to receive txt messages. Call up sprint and activate incoming txt.

have you tried a hard reset? remove the battery, let it sit for a minute and start it up again.
