New to AT&T and iPhone. Is there any kind of symbols found somewhere on the iPhone to show the user if their sent texts were successful. On my old verizon service, you got a check for text sent and received properly, an arrow for texts sent but unknown if received and a red X if the sent failed. Is there any kind of alert system like this. And yup, I did a search and came up short. P.S. I also did a youtube search for basic iPhone tutorials and tips and got a lot of junk. If any of you have a great site to recommend for tips and tricks with videos, it would be appreciated.
