BT FON

BT's incredibly clever FON network is often a lifesaver, letting you legally borrow Wi-Fi for free in many public places. And while standing outside strangers' houses. The BT FON Android app lets you automate the sign-in process, so you can walk around towns and housing estates safe in the knowledge that your phone's always seeking out available Wi-Fi. You need a BT FON username, though, so sort that out before you venture out into the scary internet-free world.
