Today's Tech: Obama overrules US Apple iPhone, iPad sales ban and Samsung teases Galaxy Note 3 and Gear smart watch IFA launch

Samsung has started distributing special invitations for an event on 4 September, fuelling rumours of an impending Galaxy Note 3 launch. The big event, titled 'Samsung Unpacked 2013: Episode 2', will take place in Berlin two days before IFA 2013 kicks off. The Galaxy Note 3, if the rumours are true, will feature a 5.7in full HD 1,920 x 1,080 display, a 13-megapixel rear-facing camera and a Snapdragon 800 processor. Also on board will be 3GB of RAM and Android 4.3 Jelly Bean. Also hot on the world's lips is talk of the launch of a new Android smart watch, called the Samsung Gear. This would represent Samsung's first foray into the wearable tech segment, and would also mean the South Korean giant beating Apple's much-rumoured iWatch - which many expected to launch at WWDC in June - to market. According to sources, the wrist-bound device will pack Android 4.3 and a clock speed of 2.3GHz.

Wikipedia co-founder Jimmy Wales, a key technology adviser to prime minister David Cameron, has rubbished the government's demand that ISPs should introduce porn filters by default. Wales told Channel 4 News the proposals were "ridiculous" and would not help stop illegal content appearing and being accessed online. Wales advises the government on open access to information online. He told Channel 4 News, "When Cameron uses the example of paedophiles who are addicted to internet porn, all that these plans would do is require them to opt in [to access legal porn]. It's an absolutely ridiculous idea that won't work." Under government plans, by the end of 2014 every new contract with a UK ISP will ask customers to opt in to receive adult content. Wales said existing legislation covering criminal activity online was already adequate. He said what the police needs are more resources to tackle online crime.

In a bit of a last-minute reprieve for Apple, the White House has officially overturned a looming ban by the US International Trade Commission (USITC) that would have prohibited sales and imports of the AT&T version of the iPhone 3G, 3GS, and 4, as well as the 3G-friendly iPad and iPad 2 tablets, starting this week. The move represents the first veto of a USITC decision since 1987. "After extensive consultations ... I have decided to disapprove the USITC's determination to issue an exclusion order and cease and desist order in this investigation," wrote US Trade Representative Michael Froman in a letter to International Trade Commission chairman Irving Williamson. Apple, responding to the news via statement, praised the decision while simultaneously taking a dig at rival Samsung. The company said that Samsung "was wrong to abuse the patent system in this way." Samsung representatives say that the company is "disappointed" by the decision. "The ITC's decision correctly recognized that Samsung has been negotiating in good faith and that Apple remains unwilling to take a license," said a Samsung spokesperson.

Android Jelly Bean adoption continues to grow after recently surpassing Gingerbread for the first time. According to new stats, Jelly Bean (versions 4.1.x and 4.2.x) was running on 40.5 per cent of Android devices as of 1 August. Gingerbread landed at 33.1 per cent, followed by Ice Cream Sandwich at 22.5 per cent. Jelly Bean first topped Gingerbread in June, according to last month's stats. At that time, approximately 37.9 per cent of Android users were on Jelly Bean, while 34.1 per cent were on Gingerbread, and 23.3 per cent were still running Ice Cream Sandwich. At this point, very few Android devices are still running the earliest versions of the mobile OS. Around 2.5 per cent are on Froyo, while 1.2 per cent have Éclair, and just 0.1 per cent are running Donut (as well as the tablet-centric Honeycomb).
