I have some family members with iPhones. They have figured out how to send text messages to multiple recipients: start a new Message, and add multiple contacts in the To line. Unfortunately, they have not figured out that replying to these replies to everyone who got the original text message.
Is there a setting that I can ask them to change on their phones to prevent these unintentional reply-all messages? Or is there a way that I can tell my iPhone (4 on iOS 5.1) to ignore reply-alls?
