you have got a good refurbished n900 i think and they are not bad usually damaged n900s are repaired with one another or with parts available and then given a shiny casing then nothing wrong with that as long as its perfect and n900s arent produced anymore so let them revive a few thousands if you want to check you need to open it ... Just enjoy man you have a shiny n900 deliverd anyway i am also using a self refurbished n900 btw check my thread
