Is there an option to be able to Reply All to a group text message that is sent to the samsung exhibit 4g? Anytime I receive a group message, it is described as a Multimedia message sent to multiple people. But when I reply to the text, it only gets sent to the original texter. Any words of wisdom on this? I've searched forever and can't find any information on this or any sort of 'Reply to All' function on the phone.
