New document reveals that The NSA can "spy on smartphones"

The NSA and GCHQ can reportedly tap into data held on iOS, Android and BlackBerry smartphones, according to new documents leaked by whistleblower Edward Snowden.

The two spy agencies are apparently capable of tapping into smartphones and downloading contact lists, SMS data, location information and other data, according to a report in Der Spiegel.

The new documents suggest that GCHQ has managed to circumvent BlackBerry's much-touted security - and celebrated the fact with a message titled "Champagne!"

According to the documents, the NSA set up working groups to tackle each operating system, though it isn't clear when. The group working on iOS exploited a feature which lets iPhone users sync their devices with their PCs. Agents then hacked into the synced PCs, giving them access to iPhone data.

The report doesn't detail how Android phones are hacked.

But the two agencies have reportedly managed to tap into BlackBerry mail - apparently succeeding where several governments have failed.

It appears the NSA initially cracked BlackBerry's security itself, but temporarily lost access in 2009 after the Canadiam firm altered its data compression methods. But GCHQ came to the rescue, apparently regaining access to BlackBerry device data in 2010. It isn't clear how GCHQ managed to get around BlackBerry's security.

BlackBerry is refusing to comment on the reports but, in line with other tech firms accused of handing over access to customer data, told Der Spiegel that it hadn't provided a "back door" to its systems.

The new report follows revelations last week that GCHQ and the NSA had cracked several common encryption technologies
