it took me forever to find this.. and a lil testing but this is what i use.
i install the arcsoft cab i will attach here, this is the one extracted from diamond.. pretty much any version works
then go into the text messaging(might have to reset) and go to mms option.. make it like my picture. name doesn't matter
then go into registry and go to HKEY_LOCAL_MACHINE/Software/Arcsoft/Arcsoft MMS UA/Config/mm1/Wspheader and change the following
X-VzW-MDN: "YOU NUMBER HERE"
Accept-Charset: us-ascii;utf-8;iso-10646-ucs-2;ISO-8859-1( u should only have to erase the last 2 semi colons)
