Demonstrating security restrictions tighter than an airport amid a terrorist threat, LOCOG has published an exhaustive list of items that you won't be able to take to the Olympics. Alongside the classic "no liquids over 100ml" restriction, LOCOG has also banned 3G dongles and the use of mobile hotspots in smartphones.
The Olympics kick off tomorrow with the Danny Boyle-designed opening ceremony - but LOCOG is doing its best to ensure a 28 Days Later-style fiasco doesn't ensue. It has restricted many items from being taken into the Olympic park. Some are obvious, such as firearms, knives and pepper spray.
But some are a little more left-field. 3G dongles and Mi-Fi style units are not allowed, and you're not meant to use your smartphone to create an internet connectivity-sharing Wi-Fi hotspot. We're yet to confirm whether there will be Wi-Fi-sensing rottweilers on-site to take out anyone doing so.
Other tech-related items that have been shunned include walkie-talkies, phone jammers, radio scanners, laser pointers and strobe lights.
Disappointed? Don't take it to heart as the chances of you getting good enough 3G signal in such a packed area to make it worthwhile are pretty slim.
