Seeing as they still have IMEIs im pretty sure they can be blocked if they are reported. I have read in the GS3 forums where some guys had gotten the phone off ebay or craiglist and VZW woupdnt activate it dues to it being reported stolen. They didnt have a 4g sim card though and were trying to get VZW to send them one so while that still leaves it uo in the air...
Im pretty sure if you use a phone on VZW that is reported stolen then they will block it and contact you, and im pretty sure theyd be able to even tho we use sim cards in 4g phones now.
When the first iphone came out I got one, I was young and stupid, and it got stolen within a month. When i called AT&T and reported it stolen they told me that it had been activated on a different account and that they were blocking it off of their network permanently and would contact the user and ask them to return it. I dont know what ever came of it cause they were supposed to contact me if they got it back, I assume they didn't, but even they could block a phone permanently back then sooo......
