Both my wife and I have Iphone 4s which for the most part have worked great. No signal problems but unfortunately my proximity sensor is not behaving. Anyway, a few times when I've sent her a text message it's shown up in an email instead of her text message screen. The from address is email@example.com, which I believe was how we were able to send MMS messages prior to true MMS being enabled. This only happens occasionally and it's happened on both plain text and pics. Anyone else seeing this? Thanks in advance!
