On a plane ride, I had no choice but to buy the gogoinflight service for 7 dollars for the duration of the flight. When I had access to it from my iPhone, my apps like HBOgo movies were really lagging, and would freeze. My Netflix would not even play at all. I have seen these "personal wifi hotspot" gadgets in electronic stores. Do they actually work ? And if so, can you use it on a plane, hotel etc ? I googled it and nothing about planes, etc, came up.
