My MMS messaging worked for the first couple of days that I had the 4S (2 weeks ago) but now it won't let me send or recieve picture messages. Sometimes the MMS would be sent at a much later time (example: a friend recieved it at 5am when I sent at 7pm the day before), sometimes when I would restart my phone, then I would recieve an MMS message... both very inconvient. I've discussed with my carrier (Rogers) and they did a number of "tests" on their end to figure out what could be causing it. They suggested to restore the phone to the factory settings to test it out and if it worked, I could restore my phone from my backup. I restored from orignal, and MMS worked, but once I restored from back up, it stopped working again. I'm content with restoring from factory but then I lose everything I have saved. Any ideas?
