O2 Free Wifi Service
I posted this a year ago and its still relevant so i thought i'd share again for all those who missed it.
I'm sure this wont be new to some of you but there may be people out there that do not know about this and could be handy. :)
Fast, free internet, for everyone, and you don’t even have to be an O2 customer to use O2’s free WiFi. Once you’ve signed up, there are no passwords or usernames to enter; you just have to be near one of their many hotspots.
they've also launched a free app which lets you register easier - available for iOS and Android - to make easy to find O2 Wifi hotspots. The app will help you locate hotspots near you and around the country.
If you’ve got an Android device you can also use the app to register for the O2 Wifi service.
