It's definitely a major undertaking. Even swapping cases might not be as
easy as it sounds. I know, I did open my 2100 case to replace the
speaker. Not for the faint of the heart. The battery recharging thing is

available. You need to be very careful. If it doesn't bother you too
much, I would suggest you leave it alone...
