WM6 Verizon Text Message and Threaded SMS Issue

[PPCFreak]

I have the WM6 on Verizon and the threaded SMS app.

It seems to work just fine for txt messages that do not come from the Verizon network.
I can send from my work via 10digit@vtext.com and I can get txt messages from other mobile carriers (T-Moblie and Sprint so far).

But so far anyone on the VZW Network can not send me txt messages.

Is there some sort of setting I am missing?

I have my phone locked to 1X only since I am in a so-so coverage area for EVDO and in basement of building during work day.

This is driving me nuts.

On Radio 1.10 if there is any difference or not (stock VZW radio).
