I'm having the same problem. I even included it in my sig hoping to get a solution. Mine is:
****Verizon Samsung U430 no MMS****
Ok just switched back to UTnT from TnT. Before I could send my phone ringtones as attachments & pictures to email@example.com. Now I get this message: "You've got a PIX message! To see it, vist www.vzwpix.com from an internet accessible computer & follow directions." Course that won't work.
Called PPC, my phone is not supported, et al. I can send & receive SMS & use the internet. What the heck is going on & how can is this remedied? Thanks.*****
