never mind...I was on the wrong menu, so I didn't see that there is an autorefresh time option...kinda sucks though, that that I can't get SMS messages immediately.
I had the same issue. I used GV SMS extensively for free SMS when I was in the UK.
Does anyone know if there is a way to make a GV SMS show up in the regular SMS inbox? That was the only irritating thing, I kept having to go check to see if a GV SMS had arrived.
