I downloaded the file from Visionary's web site, got it properly unzipped, onto the phone and used Linda file manager to run the apk file, but I do not have Visionary installed. It did install the Superuser icon, but not the Visionary icon with the yellow triangle. Any thoughts folks?? I double checked that everything is installed on the micro SD card by pulling it out of the phone and sticking it into a card reader. The files are there. I've restarted the phone a couple of times, even pulled the battery. Obviously, I have the MT4G through TMo and I have the latest OTA update prior to attempting this temproot.
