MMS on 6900

[fawkstrot]

Hey all... I'm running the 3.42 radio with the Vogue 3.02 GPS. I have the Arcsoft MMS 3.0.26.12c installed (through the BuildOS select option). I also made sure my settings for Pic/Video messaging are as follows:

"Pic/Vid Messaging:
Start>Messaging>Pics/Video>Menu>Pics/Video Configuration>Servers Tab
Edit Default (Click on default)
Server Name: Verizon Wireless
Gateway: Erase existing IP and leave blank
Port Number: 80
Server Address: http://mms.vtext.com/servlets/mms
Connect via: Internet
Sending Size Limitation: 500K Or For the Newer MMS: 300K
Wap: 2.0"

(Taken from the helpful 6900 GPS thread)

However, when I try to send a pic message it will sit and the notification pops up that it's sending, it sits and works for a minute, then a message comes up saying "Message Delivery Failed. Or Message Receipt Failed.". I have verified that they are not going through and that it's not just the receipt failing.

Can anyone help me out? Everything else, including the GPS, is fully functional.
