My trusty launch 64GB iPad Mini 4 may be retired now that I've seen the new iPad OS but I have a few questions and a couple of them may not be answerable until the new OS is actually out. 1. Is there a magnet for the pencil? 2. Will the new OS allow for Bluetooth file transfers to non-iOS devices like Androids or PCs? 3. With the camera connector cable can I plug a flash drive into the new iPad OS? Thanks!
