And as cboldt said, some people set their ipods up to lock I guess. I have two and neither of them does it but I probably could set it up that way.
I wonder if it could be done remotely? Wasn't TM on his father's plan?
My kids lock them to make them less attractive targets of theft at school.
It's an android phone, and from I see, it is also WiFi capable. I would think that access via WiFi might be possible, and looking up the ability "wipe" a phone, I learned that there are apps that can do that with a phone call to the device.
All of that is in the hands of the person who controls the device (picks apps to put on it, provides keyword or other information to the app), who may or may not be the calling plan "bill payer." The bill payer can cut off access to T-Mobile cell tower usage, without having control of the phone.
