From day one there has been issues with my iphone. The biggest being that mms messages would randomly stop working day to day. Sometimes i couldn't send, sometimes I couldn't receive and other times it was both.
Occasionally a reboot or reset of the network settings would make it better for a day or so and then it would experience the same problem as before.
I called telus twice about this and they have "refreshed" my settings whatever that means and it seemed to be good for a bout a week. now its randomly not sending things or receiving. I am getting really annoyed as my old phone had no problem sending pics or text.
