Google Android has open source Android OS, which can be available for downloads, even iOS 5 beta for iPhone techies. However, Nokia now joins the bandwagon with updateable software upgrade, even rolling the new Symbian Anna to certain power smartphones such as the Nokia N8, C7, E7, and C6-01. The new software package includes a new and interesting UI, virtual QWERTY keyboard that appears on tilt, messaging that can be done in split screen, better security, and online browsing experience.
All of this new stuff can be enjoyed in two ways. One, it can be downloaded via the Ovi Suite for PC, or it can be downloaded over-the-air, which directly comes into your cellphone. NFC support is also available on certain devices, which can be used for card transactions, train passes, and more. Graphics are now clearer, animations are much more entertaining, and the overall navigation experience is now more fluid than the previous Symbian version. Get your phones ready and download the latest UI from Nokia.
