All of a sudden I am not receiving on my blackberry the same emails that go to my computer. I read that perhaps a hard set(??) might be needed and it said on certain RIM models to insert end of a paper clip in the little hole on the back of the blackberry. How would I know my RIM model? There is a little hole on the back of the blackberry but I hesitae to insert anything there. Can any one give me any information on this? Thanks so much.
