I'm new to the whole iPhone preorder thing. I got in on the T-Mobile Jump On Demand promotion, and I was wondering if anybody can tell me when carriers usually start their preorder process? Is it the same as Apple or later? I ask because: I have to go to a store to get my "free" upgrade to the 6S/S+, I have to do it within 48 hours for priority access, and I need to plan some time for it...
They usually start at the same time as Apple does; however last year almost all carrier sites were having problems with server overload and people weren't able to pre-order.
