Hi there, I have a iPhone 4 running 6.0.1 on Straight Talk. My data works but my MMS doesn't even after changing my APN settings. Anyone know how to fix this without doing the T-Mobile SIM trick?
For the iPhone 4 and lower jailbreaking and downloading an APN editing app through Cydia was the best way I did it. I'm currently using ST on my iPhone 5 and the only method is the tmobile sim swap and editing apn settings through it. The jailbreak is still semi tethered though on the iPhone 4 so it's not that bad.
