Yea, Walmart's family mobile actually runs off of T-Mobile towers, so I did a regular jealbreak/unlock and it works fine for normal stuff.

I got mms working now though.

I added the source htt://cydia.pushfix.info in cydia, and installed the T-Mobile MMS fix for ios4.

After it installed, I went to Settings > General > Network > Cellular Data Network and added the fields as this:

APN: web.omwtoday.com
Username and Password blank.

MMS
APM: web.omwtoday.com
Username and Password blank again.
MMSC: wirelessfour.mmsmvno.com/mms/wapenc
MMS Proxy: 216.155.165.50:8080
Message size blank.
MMS UA Prof URL: http?//www.apple.com/mms/uaprof.rdf

it works beautifully now!

Well, day one of having it working. And it stopped working.

Ugh. Anyone have any ideas?

I have the same problem on my Iphone 4 with Mobile Vikings in Belgium. (KPN network)

Also tried the tmobile mms fix and changing the settings.. no luck.

I thought walmarts plan was a closed network?? I.E. they would not add a ESN?
