I see. I didn't know that about the batteries, I thought they were much simpler than that. I actually just ordered a BL-5J off of eBay for 2 bucks. I guess I'll wait a couple days and then update you. I don't have any friends with an N900 (or Nokia of ANY kind . . . all my friends use iPhones with the occasional Android phone). Thanks for your help so far on this.
