Nokia users have started to receive the Belle update for their S^3 devices since yesterday. Meanwhile, many users may have found trouble in installing their old applications. This is because the applications that were compatible with Anna are not compatible with the new Nokia Belle.
Popular applications such as Adobe Reader LE 2.5, Asphalt 6: Adrenaline HD, F-Secure Anti-Theft for Mobile, and much more are not compatible with the new Belle. Moreover the apps that are not compatible will not be displayed in the Nokia Store app from the mobile. Not to worry, these apps will soon be available for Belle.
The list of applications that are not compatible for Belle can be found in the Nokia Europe Page here.
