Can apple tell if your apple device is jail broken if you give them your serial number?

Yes, Apple can determine if your device is jailbroken by checking its serial number against their internal databases and looking for signs of unauthorized modifications. When a device is jailbroken, it may exhibit unusual behavior or have software discrepancies that Apple can detect. Additionally, if the device has been connected to their services, they might have access to logs indicating that it has been modified. However, simply providing a serial number may not reveal this information directly to the user.
