First see if your phone has ROM6! You can see which ROM you have by:

:: WorkShop ::

Connect your phone to computer with an MBUS Data Cable

Switch phone on.

Run NokTool1.8 and press Read Phone Info it will display which Rom you have in the box at the bottom right corner: DSP |ROM?|

If you have ROM6 then you can continue with the upgrade but if you have ROM5 then i'm afraid your phone is not upgradable.
