Today's Tech: Android Jelly Bean becomes Google's most popular OS and BlackBerry CEO pleads for patience following Z10 flop

Android Jelly Bean is now the most popular version of Google's mobile operating system, surpassing Gingerbread for the first time. According to stats published this week, Jelly Bean is now running on 37.9 per cent of Android devices. Gingerbread lands at 34.1 per cent, followed by Ice Cream Sandwich at 23.3 per cent. Last month, approximately 33 per cent of Android users were on Jelly Bean, 25.6 per cent were on Ice Cream Sandwich, and 36.5 per cent were on Gingerbread. Jelly Bean first topped Ice Cream Sandwich back in May, when approximately 28.4 per cent of Android devices were running Jelly Bean, beating out ICS at 27.5 per cent. Very few Android devices are running the earliest versions of the mobile OS at this point. About 3.1 per cent are on Froyo, 1.4 per cent have Éclair, and 0.1 per cent are running Donut (as well as the tablet-centric Honeycomb).

Microsoft is set to announce a major leadership and business unit shakeup this week, it has been reported. The restructuring orchestrated by Microsoft CEO Steve Ballmer would result in the creation of a "new cloud computing and business-focused products unit" and a new division encompassing all Microsoft hardware devices, "from Surface tablet to Xbox game player," as well as the company's music and TV services, according to reports. The rumoured cloud computing and business products unit is to be headed by current Server and Tools Business president Satya Nadella; co-Windows chief Julie Larson-Green will be in charge of the device and media services unit; Windows Phone Division boss Terry Myerson will take over Windows; and Online Services Division president Qi Lu, already in charge of Bing, "could add Microsoft Office and other apps to his portfolio," All Things D reported. Microsoft Business Solutions Division president Kirill Tatarinov and Microsoft Office Division president Kurt DelBene could either find themselves working for new bosses at newly created business units or even sacked. Microsoft declined to comment upon the more recent report.

BlackBerry CEO Thorsten Heins asked for patience from investors at the company's annual meeting this week, stating that the company is in a "transition" period. The request follows disappointing first quarter sales of its new flagship Z10 model. "This isn't just the launch of a new product but a whole new platform. While many will judge us on the basis of one quarter of a single product, we are not a devices-only product," he said. "This is a long-term transition for the company, but I can assure you that we're pushing very hard." When questioned about strategic alternatives, Heins did not rule out the option of a licensing deal or even an outright sale, pledging to do anything to return the company to profits. "BlackBerry will pursue every opportunity to create value for shareholders," he said. The assertion may go some way to appease disappointed shareholders and did boost share prices in morning trading on Tuesday. The poor Z10 sales was reflected across the entire range of new BlackBerry 10 devices in the last quarter, causing the company's stock value to fall by 28 per cent on 28 June. A loss is also estimated for this quarter.

Finally, Microsoft has revealed that hackers have exploited a bug in Windows that was first disclosed by Google researcher Tavis Ormandy in May. Ormandy, a security engineer, came under fire when he publicised the bug through the full disclosure section of Internet security site seclists.org without notifying Microsoft, meaning the company had no time to fix the flaw first. Microsoft released few details of the security breaches, but in a statement said hackers had launched "targeted attacks" - a term generally used to refer to those on corporate or government targets, usually to steal information or sabotage systems. Following Ormandy's disclosure in May, security firm Secunia issued an advisory which explained that the bug could be "exploited by malicious, local users to disclose sensitive information, cause a DoS (Denial of Service), and potentially gain escalated privileges." Microsoft would not say whether it believed Ormandy's exposure of the bug was responsible for the attacks.
