I love the look of the 5S/SE. It looks premium, it feels nice in your hand, it's solid, and those chamfered edges are so nice.
It's a shame they went from that to the iPhone 6 design and stuck with it all this time. It might make bigger phones easier to hold but man it just doesn't look as nice IMO. It looks like a generic round phone. Nothing stands out about it at all.
My favorite is the curved back, as is on most Motorola's and some LGs. Personally, I stick with cheap LG phones ($100 or so) that are rootable/rommable. If the phone gets damaged or I want a newer phone, no skin off my back, biggest concern is just moving Signal Private Messenger over to the new phone I get :P
We would just send the phone number to our Verizon account manager and he'd send us proof of purchase for that device and we'd forward it to Apple. Wasn't a terribly difficult process, at least in my experience.
That's an OS-independent problem ;)
You have to contact Apple and provide proof of purchase for the device to have them remove the iCloud account.
The issue is allowing that to happen in the first place, instead of locking it centrally. That's either a limitation in your MDM's capabilities, or its setup. ;-)
