iMessage going to email instead of iMessage
So my mom is sending me iMessages and some of the messages are making it to my iMessage on my iPad 2 and my iPhone 4, but recently several have gone to my email instead. I have my iPhone and my iPad associated with the same email so I receive them on both. She has a Verizon iPhone 4.
Again iMessages from others are always going through but for some reason a few of the messages from her Verizon iPhone 4 are going straight to my email and not into the iMessage app. Any ideas. I made sure the caller ID says my email address for both devices.
