Update 5800 to v40 (Product code issues)

For some of the Nokia 5800 models bought early when it was just launched in Jan 2009, the firmware upgrade to v40.0.005 is not possible. When you try to update using Nokia Software Updater, it identifies your product code and denies the update. You can get over this problem by simply changing the product code of your phone.

Currently the following two products are not eligible for the new firmware in India.
0575586: 5800 India CV B v1
0575590: 5800 India CV R v1   
Change your product code to the following product codes to get the new firmware.
0573797: APAC2 India Black
0559961: APAC2 India BLUE
0559673: APAC2 India RED
