I'm a bit confused. Does my phone have to be rooted in order to install apps downloaded from torrents? I've read through some comments on the torrents and they say you don't have to have a rooted phone. They say you just install it on your SDcard and locate it and install it. I don't have an SDcard in my phone though. Can I just put the file in the Downloads folder of my phone and install from there? I want to install JuiceDefender Ultimate.
