Hey, heads up, the SMS appears to be working fine, but MMS server settings point to Sprint as default. I'm going to try configuring it based on this thread on post 1:

I'll post back with my results. Don't apply the MMS fix update just yet, there's still hope that we can continue using the HTC messaging client for MMS and whatnot.
Update: The server edits work fine, just make sure you set Verizon to the default. It really seems to like Sprint for some reason. The only downside right now is that I cannot send MMS. I can receive though, which for me is more important since I don't send many. I'll continue working on this. I haven't tried the Manila 2.5 MMS Fix (Valkyrie) and I don't know if I want to since I have mine working the way I want, so any volunteers, please try it and let us know how it works.
