Two items today. Both AT&T and Verizon are planning to open up their wifi hotspots to their customers to encourage phone users to leave overloaded 3G and 4G networks for their browsing.
Also, they are both joining a consortium that will open all wifi networks to any users from any competitive company. The project will allow seamless transition from 3G to wifi where available. It will also not require the need to use various passwords to log on. The idea is that the phone, tablet would connect automatically, but retain a high level of security. We may see a series of area wifi spots that will greatly reduce the dependency on cell towers.
