Tell us the secret!!!
u da man!
I Just Installed the MMS Cab for verizon and Edit the registry for:
gateway: mms.metropcs.net
port: 3128
domain: mms.metropcs.net/mmsc
Now i cannot receive anymore, but when i send I dont get the error message right away. now i have a small window popup saying "sending MMS message 0%" and it stays there for a minute.
