I just received a used Apple Bluetooth keyboard I bought through eBay. I paired it with my iPad, no problem. Problem: The previous owner of the keyboard gave it a really dumb name and I'd like to change it but I can't figure out how to do it on the iPad. I've removed the batteries, didn't work. I paired the keyboard with my Macbook, renamed it, then paired it with the iPad but the keyboard still had the old name even though it showed the new name when paired with the Macbook. Any ideas?
