They just keep coming in! Right after the E71 firmware update, comes news that the E66 has also been given the new v300.21.012 firmware. Like was the case with the E71 firmware, there’s no word about the changes that have been incorporated.
The E66 firmware is available via the Nokia Software Updater and there is no over the air download ability for this Feature Pack 1 device. Please bear in mind, you will also loose all data on your phone memory when you update so make sure you create a backup before you fire up the NSU.
Nokia has been blocking the ‘hack’ through new firmwares for various devices, so if you are into that sort of things, it might be a good idea to hold on, else fire up the NSU and see if its available for your product code.
