Whenever I try to download Facebook mobile on my mobile it says 'Authentication failed.' I don't know what to do to stop this? How can I download Facebook mobile for my phone?
I'm not sure what details you need but it's a O2 pay as you go phone, it was a contract on Vodafone but I'm now using it on O2.
Thanks for your help
