Find My Phone

Jason, Jocelyn, Jackie, and Jerome arrived at school on the first day after winter break. It was January 3rd, 2030. As they walked in at 8:59, just in time for the attendance bell, they discussed the latest cool features of IOS 38 that had automatically loaded on their phones the previous night. The update also had a bug that made private "Find My" data public for phones that had updated between 1:34 and 3:07 a.m.
"Oh no!" said one of the four friends - "I just realized I left my phone on the bus!" Luckily, that bus was kept parked in the school lot, so at morning break, they hurried out to search for it. No luck. "It's gone!" said the desperate student. "Maybe it has the bug, and we can see where your phone is," said one of the others. They checked their "Find My" apps but had no luck. "We told you not to use that little phone," said the others. "You should have a larger phone like us!"

Who lost their phone?
