Is it possible to erase the current trainer data on the Pokewalker?
I recieved a Pokewalker from a friend a while ago and i noticed that her trainer was still there. I thought maybe replacing the battery would do it, but it was still there. I want to replace the pokewalker with my trainer but it always tells me that the pokewalker is used by someone else. Is there any possible way to erase the previous data?
