Today's Tech: Nokia launches flagship 41-megapixel Lumia 1020 smartphone and Samsung trumps Apple in mobile Internet stakes

Samsung has overtaken Apple globally for the first time in terms of mobile Internet usage. The figures for Internet usage on mobile devices have never been more important as shipments for PCs continue on their downward path, with basic PCs being replaced by tablets and smartphones in both the consumer and business space. The report says that while 12 months ago, Nokia led globally in terms of mobile Internet usage, Samsung (25.47 per cent) has leapfrogged both Apple (25.09 per cent) and Nokia (21.96 per cent) to take the lead in June 2013. In the US and UK however, Apple remains the clear leader in mobile Internet usage, said StatCounter. In both markets Apple holds around 50 per cent of the mobile Internet sector. In the UK, one of its strongest markets, BlackBerry has lost its number two position to Samsung.

BlackBerry has handed Indian law enforcement agencies the ability to intercept users' digital communications. According to a leaked document, government agencies will now be able to track emails and attachments sent between BlackBerry devices on a real time basis. They will also be able to check whether BlackBerry Messenger communications have been delivered or read, and even monitor what websites users have visited. A BlackBerry spokesperson said, "The lawful access capability now available to BlackBerry's carrier partners meets the standard required by the Government of India for all consumer messaging services offered in the Indian marketplace." In August 2010, the smartphone maker narrowly avoided a legal ban when it offered a series of proposals to support the country's need for "lawful access." BlackBerry communications are heavily encrypted and sent via a server in Canada, where the company is based. Indian security agencies argued that they needed access to all messages and the keys to decrypt them in order to fight terrorist activity. The company said however that it "does not possess a 'master key', nor does any 'backdoor' exist".

The British Parliament's Intelligence and Security Committee (ISC) has revealed that a cyber-espionage operation has stolen sensitive data from the Ministry of Defence (MoD), in an attack that has "both security and financial consequences" for the country. The admission came in the ISC's annual security report issued yesterday, which said, "Government departments are also targeted via attacks on industry suppliers which may hold government information on their own systems. We have been told that cyber espionage '[has] resulted in MOD data being stolen.' This has both security and financial consequences for the UK." The breach represents a significant blow to the government's cyber-security efforts, with Westminster currently ploughing millions into a host of initiatives to strengthen the nation's digital defences. The MoD has not disclosed any further details on the attack and the nature of the information stolen is unknown. Elsewhere, the ISC report said that over 200 email accounts across 30 government departments were targeted in an attempt to steal confidential data last in summer 2012.

Last, but definitely not least, Nokia has unveiled its latest flagship smartphone, the Lumia 1020, which ventures into unknown photographic territory for a mobile phone. The Lumia 1020's camera boasts a second generation 41-megapixel sensor with Nokia's PureView technology. Following swiftly on the heels of the Lumia 920, and even more recently the Lumia 925 and 928, the new Lumia 1020 sports a 4.5in AMOLED display with 1,280 x 768 resolution, a 1.5GHz Snapdragon S4 processor in the engine room, 2GB RAM, 32GB internal memory with 7GB free SkyDrive cloud storage, a 2000mAh battery, wireless charging, LTE connectivity, and a 1.2-megapixel front camera. Unveiling the phone at a New York press event today, Nokia CEO Stephen Elop said, "The Nokia 1020 will change how you shoot, how you create, and how you share pictures forever."
