GSX will warn you if you look up the device. Also, out of curiosity, why not call them in to AppleCare and save the trip? When they process the repair, they'll also see if it's locked.

What do you mean "Call them into AppleCare"? You mean literally call Apple Support on phone prior to booking a Genius Bar appointment?

I checked my iPhone in GSX (cross-referenced it's serial number), and I don't see Find my iPhone or Activation Lock status.

To be honest, Im not sure of the logistics on how/why our Helpdesk staff performs iOS repairs (other than Activation Lock makes them curse loudly and curl up in the fetal position under their desks.) Our current mobile support workflows were probably created back in the RIM BlackBerry days! Time to reevaluate them. We are using Meraki MDM now, but I hope to migrate to Jamf so we can manage all Apple devices in one solution/interface.

Not sure how it works for Enterprise, but in Edu we can call directly to AppleCare and do mail-in repairs. It's a lot more convenient than running to the Apple Store, especially if you have a lot of volume. You can also set up mail in repairs directly through GSX if you have access.

Are they doing in-house screen replacements?

No - we are not doing any physical repairs in-house at this time.

Can you post a screenshot of the Activation Lock-related settings you see in GSX?

How fast do you get your iPhone repairs back? Is the turnaround fast? 7-10 days is too long (and we don't typically issue loaners often) I think that my end-users usually get repaired devices back the same day.

If you "Search GSX" with the serial number of the unit, you'll see the following prompt:

You can also have the user's log in to iCloud.com, look at Find My iPhone and drop it out from there. It might be a good process to have the help desk do that each time they take in a phone.

As far as the speed of repairs goes, usually it's 3-5 days. We just assign a permanent replacement from a stock of loaners then repair the original unit and put it back in circulation as a loaner.

Thanks @VT-Vincent - That worked for me. I must have been trying another search field elsewhere. GSX has literally got to be the worst web interface I have ever used!

My Helpdesk staff does work with the end-user to disable Activation Lock from iCloud.com, however, once disabled from iCloud.com, the device will reenable Activation Lock automatically once a wi-fi or cellular network connection is established. I have confirmed this will Apple Support. The only way to ensure it doesn't get enabled is to power-off the device and pull the SIM for good measure. Of course, its possible to not notice that a device is powered-on if the screen is failed, etc (this has tricked us before and now we have a run to power-off all devices before repairs) Apple told me that the Apple Stores in US have a firewall rule (or something) that stops the automatic re-enabling of Activation Lock from their retail store Wi-Fi networks.

I guess we need to stock up on loaners.
