I dont know, I am out of contract with them and when their CEO stated that they would be unlocking the phones, I sent my contact an email asking her to start the process. The reply I got is posted a few posts earlier.
I suggest that you email them saying that you understand they will be unlocking them from 10/11/09 and will yours be OK for unlocking.
Given that you have no term contract with them, I imagine that they would have to. On PAYG do you have to given them 30 days notice or anything?
