I checked a number of sites talking about MMS for CDMA on ALLTEL and from what I gather there needs to be a port, not sure if it is just port or mmsport but I have tried to edit using Root Editor or Astro but can't seem to edit the apns-conf.xml file.
Could you make another Alltel MMS Fix.zip file with this line for CDMA??
Not sure if it is the right one but here it is...Remove the spaces in the h t t p (can't post links like this below I guess, not approved yet)
<apn carrier="CDMA" mcc="310" mnc="120" apn="" port="" mmsproxy="" mmsport="8080" mmsc="h t t p://mms.alltel.com/servlets/mms" type="mms" />
