Nokia’s Ovi Store for Symbian apps is now powered by Nokia Drop, allowing you to wirelessly push apps, themes, ringtones and wallpapers to your handset. This basically brings a quick and easy way to install content on your device as you don’t have to deal with SMS confirmations or use any external plug-ins.
Turning auto installation of apps means that you won’t even need to confirm that you want to install new software on your phone. To benefit from it, you need to use Internet Explorer, Firefox or Chrome (sorry, Mac users, no Safari support). Nokia Drop is compatible with S60 5th Edition and Symbian^3 devices.
