My grandkid passed me his ipad 2. it was jB'd Grand kid is touring India. I got message "upgrade to 6** available for this device when i turned it on this AM so i said OK. got a pic of USB cable pointing to iTunes icon. Took me 2 hrs to figure out (realize that it meant plug ipad into Mac. now mac says "iTunes has detected an iPad in recvery mode. you must resore this iPad before it can be used with iTunes."
