Nokia has just released a firmware update (v30.0.011) for the 5800 XpressMusic. Despite the huge version number change, the update does not seem to be a major one, mainly bringing bug fixes and speed improvements, as well as a home screen email plugin that may not show up until you hard reset the device... The update is available both via the NSU and OTA as a 4 MB download.
