As most of you know, the $119pm VDSL2 unlimited plus package (no P2P throttling...supposedly) now no longer exists.
Instead we have a single unlimited plan for $109 pm which also promises no traffic shaping. I called Slingshot yesterday to confirm that I would be automatically "downgraded" to this cheaper package and it turned out not to be the case - I had to request it.
Unless we hear otherwise from Slingshot re: the automatic changing of the package, I recommend you give them a holler and save yourself $10 per month.
