I have one of those smart phones and i'm using it at the moment to use my laptop IT connection. I wonder if i can use it to play online games? I guess it depends how fast the network is. Sorry not really a FFXIV post
I used to use my blackberry to do this very thing to play FFXI while on the road. Worked fine for it, didn't notice any issues other than my laptop isn't the greatest. One thing though is it will cut out for a bit when you get a txt or a call.
