How to Use the TextNow 4.0 App to send unlimited texts on the iPhone

TextNow is a great App for the iPhone that allows you to, for a $1 initial fee, send unlimited text messages to any other TextNow user without using any of the precious limited texts on your AT&T plan. The App is very easy to use, requires only a modest amount of additional money to keep using it forever, and will probably wind up saving you money in the long run by cutting down your monthly billed texts.
