I paid full price for my iPhone 5 to keep unlimited yesterday. I received a txt stating I was close to using up my preallocated data this morning, logged into account and they had moved me to a 2gb plan. After talking to verizon they put in a feature request to have it added back in the next 3-5 days and that it was a glitch on their part. The upgrade was from iphone 4 to iphone 5. You may want to verify on your account it didnt change.
