I have an iphone4 that's updated to all the current updates. I've been getting text messages from my own number saying that I have a new pixflix message and to login online to view them. I don't understand why I'm getting these because I can get picture messages just fine on my iphone. I never got these messages before until 2 or 3 days ago. I check out the messages online and they're just plain text messages with no image. It's really just a regular text message that never reached my phone but goes to my pixflix account instead. Why is this happening?
