Just read here that I should be expecting att to push an upgrade to my phone, and that it will include Samsung Knox security software and a new locked bootloader. My phone is rooted, and I am worried that this update will jack things up. At least it would on the Iphones, I am relatively new to the android platform. I mainly rooted, because I wanted to set up a few tasker tasks. I haven't played with any roms yet. Should I not upgrade? does it un root your phone?
