In today’s mobile news roundup: A battle ensues over the iPhone trademark; Vine now aged restricted; and BlackBerry Q10 won’t arrive in the US until Q2.

Battle for the iPhone trademark

When you hear the word iPhone, you automatically associate it with the Apple brand.  But according to sources, the trademark may be awarded to Gradient, and be used in Brazil.

According to some sources, the Brazilian Institute of Intellectual Property may award exclusive trademark to Gradient on February 13, 2013.  The company filed for the iPhone trademark years before Apple launched its iPhone, and stated that they have the rights to the iPhone name until 2018.

The iPhone trademark was acquired by Apple from Cisco in 2007, and it wasn’t until last December that IGB Eletronica SA, a company that resulted from the restructuring of Gradient, started using the iPhone name.

Gradient says it’s open to a dialogue with the Cupertino company, which means the Gradient will probably drop its iPhone claim for the right price.

Vine now aged restricted

Vine, the video-sharing service acquired and recently launched on iOS by Twitter, is all grown up.  The app updated with a 17+ age restriction, a smart addition since Vine’s mounting controversy over easy access to pornographic content.

Vine’s Terms of Service doesn’t prohibit mature content as long as the user is comfortable with what he or she is uploading.  It also didn’t help that a raunchy clip was chosen as one of Vine’s Editor’s Picks, a move that was quickly dismissed as an error.

Vine launched in the App Store last month, and we all know that Apple is not too keen on allowing apps that make it easy to find porn.  Despite fears that Vine would be ousted from the App Store, it’s remained intact, albeit altared.

Here with his full analysis on Vine’s rather mature decision, along with his thoughts on other social media sites like Pinterest that seem to be “growing up” before our very eyes, is Contributing Editor John Casaretto, who appeared on this morning’s NewsDesk show with Kristin Feledy.

BlackBerry Q10 won’t arrive in the US until Q2

BlackBerry fans in the UK, UAE and Canada were the first to get the Z10, the new multitouch smartphone from BlackBerry, and the phone maker reported that early demand for the device is so far better than expected.  Some retail shops even reported that the device quickly went out of stock in a matter of days.

The Q10, the smartphone that features a touch screen as well as a physical QWERTY keyboard, will arrive in March or April in other countries, but in the US, it won’t be available until May or June.

BlackBerry CEO Thorsten Heins stated that the US release of the Q10 will be eight to ten weeks after the Z10 gets released by UK carriers.  The Z10’s target US launch is in mid-March which means the Q10 will probably arrive in May or June.
