Ok first off sorry if this is the wrong section but I thought this would be ignored if put anywhere else.

So I just got the new metro pcs droid and I was thinking of trying PL on it. I just wanted to know would it do anything like slow my phone down or give it a virus? Would it have any effect on my phone at all? I'm still kind of learning how to eff with it so I need someone to answer those questions for me. Another thing is, do I need to have wi Fi connection for anything on the android? Or is there a way that I can be away from wi Fi yet still play the game?
