It doesn't turn on anymore. It had about 90% charge friend was looking at the o.s. version, was jailbroken by previous owner. Put it down to talk to someone looked back on the desk and it was off. I thought it turned itself off because of inactivity, when we tried to continue using it, the ipad wouldn't turn on. Has anyone else out there experienced this? I bought this unit used. It's a 64GB WIFI only model 1st gen.
