Although at some point next year MeeGo is due to arrive on Nokia smartphones, Nokia isn’t abandoning Symbian even though the Symbian Foundation recently said they would become just a licensing body and Nokia has now taken command of developing Symbian.

Thus according to an article over on Techtree by Samir Makwana, and by way of PC World, the mobile phone giant is gearing up to push out 4 or 5 upgrades to their Symbian operating system over the next twelve to fifteen months announced Nokia at the International Mobile Internet Conference in Beijing.

Apparently in excess of 50 enhancements will come with the 4/5 upgrades to Symbian including a more flexible home screen, new look and feel user interface, better software experience and an updateable HTML5 browser can on the cards for Q2 and Q3 of 2011.

As for those dual-core phones, Nokia currently uses an ARM 11 600 Mhz processor; however during the conference the senior manager at Nokia China, Gunther Kottzieper showed off a slide which listed Nokia’s plans to use a 1GHz processor along with a better graphics chip in smartphones in the same Q2 and Q3 2011.

Furthermore, Nokia also apparently announced that they plan on releasing smartphones with a dual-core processor along with “true zoom camera” functionality either by Q4 2011 or early 2012.
