I will be receiving an N900 tomorrow that is supposed to be completely new. Is the "life timer" function mentioned above available on the N900 like in other Nokia phones?

If it is, I'm have no idea where this information is stored. I'm guessing flashing the N900 would definitely wipe that information?

I'm looking for a certain way of knowing a used N900 - aside from common sense. Are there any tricks someone could provide.

Thanks,

Abe
