A new report from browser maker Opera has shown that Facebook is the most popular social networking site among mobile web users, with the website seeing growth of 600 per cent last year.
Facebook overtook VKontakte, a Russian website, to top the mobile social networking table among users of the Opera Mini browser in 2009.
However, the social network with the biggest growth in mobile usage was microblogging site Twitter, which saw an increase of 2,800 per cent in unique users over the course of the year.
All of the main social networking websites saw mobile growth in 2009, apart from Friendster.
Opera's figures also reveal an 11 per cent rise in mobile web users between November and December 2009.
"The divide between the mobile web and the web accessed on PCs is now disappearing," says Jon von Tetzchner, co founder of Opera.
"People want to use the same sites, regardless of whether they use a phone or PC to access those sites."
Over 65 million of Facebook's 350 million active members currently access it through a mobile phone or other handheld device, according to statistics from the social network.
Those who do so are nearly 50 per cent more active on the website than those who do not use the mobile version of Facebook, it says.
