Samsung has won a major battle in its ongoing tussle with Apple, after an Australia court overturned a ban on the sale of its Galaxy tab in the country. Apple had won an injunction against Samsung in October preventing sales of the Galaxy 10.1 tab, accusing of it copying its touch-screen technology. Samsung has since redesigned the tablet. The overturning of the ban is likely to provide a big boost to Samsung ahead of the Christmas shopping season. Although the ban will remain until December 2, 2011 & there is a possibility that Apple may appeal against this decision in near future.
