Luckily, we're testing the new Zebra's at my store, but talk to your leadership and let them know it's not that hard to bring the iOS devices back from the "Apple logo of death." Just plug them into a laptop, hold power and home until it goes into disk mode, connect to iTunes, click restore & update, then call CSC when the device is back to factory defaults and have them push you the profile for tcwireless.
I have to do this at least 4 or 5 times per week with iOS devices at my store and I can't imagine where we'd be if we had to send them out every time we found another device that won't boot past the apple logo. The agents on the line with CSC are always like, "um..how did you recover the iPod from that apple logo screen? We always tell stores to send them out for repair?"
