Remember that AT&T Carrier File Update that was received a little while back? It was Carrier File Update 5.6 and it came not that long after OS 3.1.2 was released. Unfortunately at that time, there was nothing in regards to what it was doing or fixing or adding. Also, just as an FYI, Carrier File Update 5.5 was the one that enabled MMS messaging.

Anyway, I would imagine that most people just did the update without question, but still, it is nice to know what it was for — even if that ‘what for’ comes after the fact.

Thankfully in this case it was an update that offered a simple fix. According to iPhone Savior;

“When sending photos or videos in an MMS message, the progress bar would stall at about 90% then result in an error ending with a (!) red exclamation point next to the MMS message. The associated message failed to be properly sent, though standard text messages worked as normal. The 5.6 patch addressed that particular MMS issue.”

Personally, I cannot verify any MMS trouble that was happening in regards to sending MMS messages, mainly because I still have yet to send or receive one. But I guess I should still thank AT&T for finally allowing my iPhone to do what my basic free phone could do several years back.
