Text messages on iPhone 3GS

[Little-Acorn]

Here's the world's dumbest questtion, probably from the dumbest 3GS user:

How do you send/receive text messages on this thing?

I'm a complete newbie in iPhones (obviously). I can make and receive calls just fine. But I can't find any icon or whatever, for text messages!

How do you do it?

You are looking for this green icon that you see in the lower left hand corner of this pic.

You can then click the square in the upper right hand corner as shown in this pic

In the upper line if you click the + you can add contacts from your address book or you can manually enter in the number. In the line next to the camera icon click there and your able to type out the text.
