London's Underground Platforms To Get Wi-Fi Prior To Olympics
London actually doesn't have too many Wi-Fi hotspots (at least for those without a BT account), but that should be changing in the run-up to the Games. A trial has already been completed, and by the time the events kick off, the entire Underground should be piping out Wi-Fi to riders. A total of 120 stations around London will be outfitted by June 2012, and as we alluded to, BT customers will be the only ones who have access for free.
If you're on O2 or Vodafone, you can also connect, but there's no telling how much it will cost. Also, the Wi-Fi will only be available on the platforms, not while riding. That's a big pitfall, but hopefully it'll expand in time. There's also a good chance that these hotspots will be crammed during the Olympics, but hopefully they'll be useful right after the games wrap up.
