How can I force MMS messages to retry?
Got to the bottom of this. If your data connection isn't on when someone sends you an MMS, the download has a tendency to hang. If you shut off the connection to save battery or have any app that does this (like Juice Defender), this will happen to you a lot. Go into the MMS app's settings and turn off the "auto retrieve" option for MMS and you should be right as rain.
