Imagio- On Alltel cannot get MMS To Work

[ahll22]

I have a Verizon imagio. I'm still an alltel customer. Everything works fine except the MMS. I cannot send or recieve pictures. I got the data connection to work. I changed the mms options to alltel found in various threads on here...but still no luck. Is there anybody with a fix or had that similar problem. Thanks in advance.
