The C7-00 runs the Nokia (Symbian) Belle operating system. Nokia Belle supports six home screens, each with re-sized widgets that the user can customise. Nokia released the Nokia Belle update via Nokia Suite (v3.3.86 or higher), with Anna previously released through FOTA or Nokia Suite (for PC or Mac) or Nokia Software updater on 18 August 2011. Nokia (Symbian) Belle v.111.030.0609 has been made available on 7 February 2012, along with other devices in the original Symbian^3 line-up. Several countries (such as Australia) do not have the Belle update available for the Nokia C7. There is no current release date scheduled and it is not clear if the update will be released for the countries that do not currently have it available. If a phone has an IMEI indicating it is from one of these markets, it can not be updated to a Belle release.
