My wifes iphone 5 is acting funnny. Often times she is getting no cell service, while my iphone 5 is. imessage goes from green to blue and back and forth, while i have no issues. This is all cell signal, not on wifi. She is also getting texts from "unknown" and the message has no content. I guess i will just schedule a genius appointment and see what they say. We bought the phones about 2 weeks ago. I just want to exchange it for a new one i guess. Thoughts?
