Never use my phone for anything other than making call's, receiving text message's or the alarm system as we cannot rely on the power staying on overnight.In fact that is one of the reason's I only play low stake games, because we have had times where the power has gone off without warning and I have lost internet connection while I am playing on-line Poker.
So had I been playing on my phone I would still lose connection to the internet, so it wouldn't help.
When the fun Stops, STOP!
