now 2.2. My files when I link via USB never show SD card. It is installed and working. (also say no name on HD when I post it to my OSX desktop.) Questions 1. Where is my SD card on file structure? 2. How to write and save apps to SD card from phone itself? 3. I had SD card issue prior to new build then did had reset and went to sprint where they installed 2.2 for me. Should I have done something else? thanks epic world!
