software update for some Asha phones

Nokia announced that some of its recent Asha handsets are getting a software update starting today, April 7. Owners of the Asha 500, 501, 502, 503, or 230 should receive “an important push notification” letting them know that an update is available. Users can also manually check for the update by going to Settings > Phone Update.
The update brings Nokia’s free MixRadio music streaming service to the Asha handsets (sans the 230 model) in select markets. Moreover, the camera experience on Asha devices will be improved after the update, offering a panorama mode, and a voice-guided selfie feature. Photos will be stored automatically (or manually) on Microsoft OneDrive - each user has 7GB of free space. An enhanced Fastlane interface, and new parental controls are also included in the new update.
