iPhone is first smartphone widely used in Wi-Fi Hotspot
There are probably many statistics in the Internet to confirm this. But based on our experience from FirstSpot, iPhone is really the first smartphone widely used in Wi-Fi Hotspot. In fact, before iPhone, we rarely encounter any technical issues/requests from smartphone “client”. Most of the FirstSpot-powered Hotspot serves client devices originating from PC and PDA. So the old version (like FirstSpot v4), apart from PC browser, we mainly test Windows Mobile (which powered most of the PDA in the “past”).
BTW, we see the decline in PDA usage and in fact Windows Mobile is moving more to smartphone too.
