Mag-FB na lang kayo using your phone. Hindi worth it pag na-suspend or na-fire kayo. Pag napansin yan sa logs, yari kayo. Payong kaibigan lang. BTW, this is from I.T. perspective. Apart from bandwidth usage, security risk din kasi ang social networking sites. Ginagamit for phising and other malware ang FB. Adn yun nga, loss of productivity from the HR's perspective.
