Today's Tech: iPhone 5 launch date rumoured, Facebook scouts London's engineering talent, O2 rolls out free Wi-Fi in the capital

There's no getting away from it, any iPhone 5 news is big news right now. And a fresh revelation today ventures that Apple's fervently-anticipated smartphone will be released under two months from now on 21 September. A French blog is responsible for the latest scoop, as in customary fashion the online community gradually pieces together the jigsaw for a major product launch before the manufacturer even mutters its name.

London will certainly be afforded a fair amount of attention over the coming weeks and the city has been popping up frequently in our headlines before a single opening ceremony firework has even had the chance to explode in the capital's smoggy skies. First, we have news of O2's Wi-Fi rollout across parts of Central and West London as the mobile operator offers free Internet access for anyone roaming the streets within its new outdoor network. The scheme is financed through advertising deals and means buying food and drink of no nutritional value from McDonald's and Starbucks just so you can use the establishment's Wi-Fi is, thankfully, no longer necessary. (When you're in the West End).

London is also the subject of Facebook's attention today, as the company seeks to pluck the best software engineering talent in Britain for its Covent Garden HQ. Laying on some welcome flattery, Facebook describes our city as having "a vibrant local startup community with lots of great technical talent."

Maybe working for Facebook is now the only way to enjoy care-free office hours immersed in the site, as a new study says the social network in the most blocked website among UK businesses. 69 per cent prohibit in-office access to it, while 62 per cent block YouTube. With 45 per cent going as far as banning private email accounts, do you think our bosses go too far with limiting Internet access?
