My iphone 4 is being stupid?

Alright, so when I got the iOS 6 update, it wouldn't let me send, only receive, but then I fixed it by just continuously restarting, hard reset, and resetting network settings several times.
Now it's been 3 days since then and now my phone won't send OR receive messages. (It says it sends but noone actually receives it)
Has this happened to anyone? Can anyone help? Please?

Restore it using itunes, this may fix your problem…

Stop buying apple products

The old IPhones are going to act stupid and slow and barley compatible whenever a new IPhone comes out. So for that really old iPhone you shouldn't keep trying to fix it. Just switch to team android? Galaxy they are much netter than apple
