@rik AT&T. Hope to switch to another carrier soon. Interesting about texting on 4G. I just tried and it wasn't working at all, then I restarted the phone and it is working fine. I couldn't get it to send images earlier and now that is also working. I even texted some 60mb tiff files and it sent them no problem. It looks like I can both send and receive long lines of text and images with wifi on. I basically never text and not in 4G, so it's hard to make a comment about reliability, but it seems to work at the moment.
