From what I understand the face to face interviews aren't until November, so they will probabaly get rid of all the september (6th, 13th and 20th) arrivals before they sort out the new applicants. On the plus side, if you had failed the phone interview they probably would have sent out your generic rejection letter straight away, rather than keeping you waiting, so I'd stay positive. If you don't hear by October, I would just give them a ring or email and ask, but wait until October as like I say they need to get the three batches of people going to florida out the way first.
