Not an iPhone person, but I've got a question on the update. My son has an iPod touch he texts with through an app (textnow?). He texted me yesterday and said there was an update to his iPod available and asked if he could. I said go ahead, but it may take a while. Anyway, after the update, he tries to text a friend from school. There is some confusion on the other end of the texts, and it turns out the texts were going to the girl's mother he was trying to text. My wife also received on her iPhone all of the texts, both from my son, and from the other mother.
My son's iPod is linked to my wife's apple ID, which I assume is how part of this happened. Is this some known new feature of the update, or did something go haywire through the update?
