Smart switch won't download on my S4. T mobile techs couldn't get their machine to do it either. I'm stuck. I can't access my address book. The tech got my google book, but it's only old numbers from years ago. All the new ones are in the phone book. I'd love to bring in my MSN contacts from my PC. I can't get my phone to talk to my PC either. I think there may be something wrong with my S4. THANKS for your help! Lyn
