Reposted from Howardforums: http://www.howardforums.com/showthread.php/1790636-iOS6-1-Jailbreak-MMS-Bug-Or-new-status-quo So, I jailbroke my iPhone 5 (Factory Unlocked GSM) using the evasi0n jailbreak when it came out in an effort to prevent iOS from automatically deleting my MMS/Data settings every two weeks. Before i did the update to 6.1 (from 6.0.1, via itunes backup/restore), MMS was working in both directions thanks to the t-mobile sim swap trick. I do not, nor have i ever, had an unlockit.co.nz profile installed. The new issue that i've encountered and verified with a friend who also has the same issue and is on straight talk w/ a jailbroken iPhone 5 (ATT GSM), is that neither of us are able to receive MMS messages from non-Straight Talk users (including iPhones w/ iMessage turned off). We can both send successfully to non-Straight Talk users, but not receive. I asked my brother who has an HTC OneX on ST to send me a test message and I WAS able to receive that. However, when I requested test messages from friends/family who are on Verizon, Sprint, T-Mobile, and Virgin Mobile; I was unable to receive the messages. The people sending the MMS messages to me all received "Delivery Report: Rejected" and the messages were never received by me. For the sake of science, I sent test messages to all of these people from my phone and was able to successfully send MMS to all of them. Only incoming messages are not working. This makes ZERO sense, I know, but it is the truth and verified by myself and my friend with the same setup. I'm wondering if anyone else who thinks that their MMS is "working", is actually only able to SEND MMS, but not able to receive. I know that I was able to receive pre-jailbreak and pre iOS 6.1. The only variable that I have not been able to test myself was whether this issue is caused by iOS 6.1 or the jailbreak because I did both within hours of eachother and was not aware of this issue until yesterday. My MMS settings are all there in the Cellular Data Network menu. I initially had TetherMe unlock the menu, but uninstalled that and switched to EditAPN thinking that maybe there was an issue with TetherMe that caused my problems, but encountered the same result. I also called ST and had my device reprovisioned thinking that maybe there was a network issue that was causing the problem... again, no workie. To summarize: I CAN SEND MMS to EVERYONE I CAN RECEIVE MMS from iOS users on Straight Talk (w/ iMessage off) I CAN RECEIVE MMS from Non-iOS users on Straight Talk I CAN NOT RECEIVE MMS from ANYONE on SPRINT I CAN NOT RECEIVE MMS from ANYONE on VERIZON I CAN NOT RECEIVE MMS from ANYONE on T-MOBILE I CAN NOT RECEIVE MMS from ANYONE on VIRGIN MOBILE Because I know people are going to say something about what my settings are, here is a screenshot. Can everyone please test this, iPhone or not and report back. Thanks, Craig *edited to include further testing:: Tried sending myself a MMS from my gf's VERIZON iPhone 4 w/ iMessage turned off, was unable to receive it. So, Im unable to receive MMS from ANYONE who DOESNT have Straight Talk regardless of their device.
