Program your unlocked iOS5 iPhone for SIMPLE Mobile service.
Two-way MMS programming for iOS5 at http://bit.ly/iphone-mms-fix
UPDATE! For iOS6 see below:
This method was tested on a factory unlocked iPhone 4S after upgrading to iOS6. No need for jailbreak!
STEP 1: Go to "Settings", tap on WiFi and temporarily turn it OFF
STEP 2: Back in "Settings", scroll down to "Messages" and tap to open it. Make sure MMS is OFF.
STEP 3: Go back to "Settings", tap on "General" and then "Cellular". Make sure "Enable 3G" is OFF & "Data Roaming" is ON.
STEP 3: Scroll down & tap on "Cellular Data Network"
STEP 4: Under "Cellular Data Network" put in the following:
Cellular Data APN: simple
MMS APN: simple
MMS Proxy: 126.96.36.199:8080
MMS Max Message Size: 1048576
MMS UA Prof URL: http://www.apple.com/mms/uaprof.rdf
Leave all other fields blank
STEP 5: Click on the Home button to go back to the main phone screen
STEP 6: Go back to "Settings" one more time, scroll down and tap on "Messages" and turn it ON.
STEP 7: Press the Home button and you're set to send & receive MMS on SIMPLE Mobile!
Once you have set it up and tested to see it works, you can re-enable WiFi, turn off Data Roaming (SIMPLE Mobile doesn't roam on data anyway) and turn on 3G (or leave it off if you're not in a 3G area for at&t devices on our network).
