Michele is having issues with her iPad 2. The Wi-Fi is dropping out and her apps disappear and reappear. Is it wearing out? Leo says that what Michele is dealing with is a "Springboard crash." It may be corrupted. She should try to backup her iPad, which she should do regularly using iTunes. Once she's got it backed up, she should do a complete factory reset. It may even need to have a DFU reset.
Seven has been having issues with his iPhone and the Apple store says there's a bad app causing the problem, and he should wipe it. When he restores from iCloud, however, that app will come back. Leo says that the Apple Genius isn't being much of one this time. Apple vets all the apps, so it's unlikely the app is the culprit.
