Today is my first day with ultra. When I tried to configure the APN to receive MMS it wouldn't save and the proxy address (a field left blank on the instructions ultra has) remained highlighted. I called Ultra and, after a long hold time they told me I need to contact Nokia customer service and ask for a 3rd party application to make MMS work. Of course, there is no customer service until Monday and I tried to send an e-mail, but for some reason that won't work either. Anyone know about this?
