Finnish-German telecom equipment maker Nokia Siemens Networks (NSN) said Monday technology it sold to Iran in 2008 could be used to monitor calls, but denied claims it can be used for web censorship. A petition calling for a boycott against Nokia has begun circulating over the Internet, claiming the technology had helped Iran to monitor mobile phones and read emails during the recent post-election protests. At least 17 people have been killed in Iran in unrest that rocked the country after the landslide victory of President Mahmoud Ahmadinejad in the June 12 presidential election, with the opposition claiming massive fraud. “There is a lot of misinformation out there,” NSN spokesman Ben Roome said, pointing out that NSN is a separate organisation from Nokia.
