I just got this phone and, thus, a new phone number. I'd like to text a group of contacts (~60 people) and tell them. Can I do it? I put my cursor in the "To:" textbox and then press the icon that lets me add people from my contact list, but after I select them and press "done," it says "The message must contain valid recipients and content." I already typed out the body of the message, so I assume it's the contacts which are causing me problems.
