Hi everyone, I just thought I would write to tell everyone that I have had some limited success when inside some buildings where I have been able to mark down points of interest and have an accurate location and report when I get near them. The key thing is to make sure that the GPS signal quality is good, and you are good to go. The building where I have had success is a rather large building, where any kind of radio signals can be spotty. I was also wondering what is the best way of playing Four Square and sharing points of interest?
