Hello all, I have been an iPhone user for the past 5+ years and just traded it in for an S4 last night. I have one major question I'm hoping someone can help me with. I made the mistake (now looking back) on clicking the "Messages" icon under the pre-installed apps. I now realize that is called/considered ATT Messages I think? My question is...HOW CAN I GET RID OF IT? I am getting texts from people and now it's going through that system rather than the regular "Messaging" system on my home screen. How can I turn it off, sign out, completely delete it, etc.?????? Please help Thanks!
