Is there any plan that offers truly unlimited "3G" equivalent speeds? "Up to 2G speed" is an unusable scam. I used to tether to my phone on a truly unlimited 3G connection and that was what I used for home internet. Netflix, YouTube, etc worked great. Online games did not due to latency.
It seems that most carriers are trying to implement this in a roundabout way by letting services send video at reduced data rates in exchange for the data not counting against the user's data plan. What a complicated mess, and very scary with regards to net neutrality.
