I've heard of people leaving it on for months at a time, some even claim to have never turned it off since buying theirs... if it's anything like a laptop or computer it should be fine, i've had a macbook pro for almost 2 years now and turned off only maybe 10 times since i've bought it.
I can't remember the last time i've turned my desktop off.. either way, i'm going to try it after the next unban is released... hopefully it works, if it does i'll post it... it might just be the longer term solution we need right now
I have been using a id with psid all week and so far so good,Sadly using unbanned 2 of my accounts got banned I dont play Blops 2 or online games.
I sync with psn every so often,so the rumors about its just Blops 2 don't hold much. If you even try login to black ops 2 servers its pretty much a instant account ban. If sign in on CFW then its luck of the draw.
