Preventing reply-alls from Group MMS text messages? 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?
Unfortunately the current version of iOS doesn't natively give us much control over something like that.

As I'm sure you are already aware of, it does allow us to turn off Group Messaging (and MMS Settings > Messages). However, that would defeat group texts in general - not just replies.


.....Maybe the next OS will?
