I am sure this may be an old topic, but i had been using the ATT messages app. While it works, it still has many problems. It can actually get annoying. And well, majority of my friends have iphone, so the group txting is a never ending story, so I have been sucking it up and using the att app. Is there any other app that I can use for group txting with iphone? nothing like whats app or kik tho. Just regular group texting.
