Hello, I just bought an unlocked iPhone 4S and I am trying to get my Softbank Prepaid card working with it. I followed to following guide: http://csi.nfshost.com/2010/03/how-to-use-softbank-prepaid-on-your-us-iphone/ and http://jeisu.wordpress.com/2010/10/...-iphone-4-work-with-softbank-prepay-in-japan/ Calls are working fine, but I can't figure out how to set up MMS correctly. I followed the instructions I found online and went to http://www.unlockit.co.nz/ (I also tried apnchanger.org) and chose Softbank Prepaid from the list and installed the profile. I also put my softbank email address into Settings -> Messages -> MMS. However, receiving or sending messages still does not work. Also, if I go to General -> Network I can't access the APN settings, does that matter? Is there any other way or do I need to wait for a jailbreak? Thanks a lot for any ideas.
