I will first change the casing from black to white. If all works fine, I will try to remove the glass from the old screen (as I already ordered new glass anyway). With 99,99% certainty I will fail to remove it without breaking rest of the lcd.

After failing, I will proceed to the local Nokia repairshop where the brand new screen along with installation costs 125 EUR (151 USD or 98 GBP). It is the same cost as the screens are sold at e-bay and it is instantly available...
