Missing Text Messaging Option in Sprint Touch Pro 2 System Settings

[Pharodox]

I seem to be missing the option to enable threaded text messaging in my settings system menu for a Sprint Touch Pro 2. For some odd reason when looking at a text message in Touch Flo, the message is not threaded. The conversation shows all of my sent on top, then all the received on the bottom. I have the enable threaded text messaging option hAndyUtils checked, but it still does not thread my message.
