I an a new blackberry user and I have a Blackberry 7100i. I would like to put a media player on this device but I have not figured out if it is possible. I found out that adobe flash is too large, but I can not find any information about windows media player.
This is not possible. You will need to purchase a newer device (such as the 8350i) and utilize the RIM-supplied media player. I also recommend purchasing a high capacity memory card.
