Hi all, does the phone need to be activated to install an app? I have an older Optimus that hasn't been activated for about a year. I want to experiment with rooting it and hoped I could play with this. I can access the Play store through WiFi but when I logged in and installed File Manager it actually installed on my Samsung Galaxy that uses that gmail account. What the heck? I have gingerbreak copied to the SD on the Optimus but need a file manager to reach it, I think. thanks.
