nope, on the iPhone until now Unlimited meant exactly that. Wife was hitting 1Gb some months at her old job because she was streaming (Not allowed really). Weve recently moved her to a HD2, and shes still hitting it hard and managing 500Mb of so per month.
Hmm, I was under the impression unlimited on all phones was the same as unlimited ISPs, unlimited within practical and fair usage, even if the cap was a hefty 2gb, its still a cap.
there is a fair use policy, but how do you prove fair use?
as I said earlier, I bet a lot of these high use people have their phones jailbroken & are either downloading torrents, etc. as well as maybe tethering their phone to a computer.
