Does receiving work for all of you getting send errors? First off, is everyone sure they have their settings right? No message center number, email center number, or mms gateway address, they should all be blank. MMS URL is
http://mms.vtext.com/servlets/mms for verizon, or
http://mms.sprintpcs.com/servlets/mms I think, for sprint. Also, go in to the registry, HKLM/Software/Palm/Varnish/Messaging, and make sure the value for mmsc is the same as the gateway, I found that when I changed mine in the settings in the program, this did not change.
Anyway, this is the error I get.
Message could not be sent. An unspecified error(0x84) occurred while sending the message. Originator Address Not Found. That's the error I get when I try to send MMS.
Receiving works fine.
