Iphone Text Message Problems?

I have an iPhone 4 and for the last hour, every time I try to send a text message or iMessage, the message will disappear from the text screen before it's finished sending.
Has anyone else had this problem? How do I fix this?

No this is for sure a problem with the phone, I suggest you take it into your local network provider for them to sort it out.

When i send a text why do it sent it twice

I've lost the message icon on my phone. I don't know what happened to it. How do I get it back on my screen. When I get a message, it shows up at the very top of the screen for a moment and then disappears. I do not have anything to click on to send a message. Suggestions?
