I have an iPad mini Wifi 64GB model with iOS 6.1 on it and its jailbroken. It's been working completely fine for the past month or so and just a few hours ago, I lost the ability to send images over iMessage. I tried resetting network settings and turning it off and on as well as a double hard reset. Nothing's worked so far and to make things stranger, I haven't downloaded anything from Cydia in about a week. Any suggestions?
