Carl Williams writes, "“Unlimited” data plans are all the rage again with cell phone companies. The last time we saw this was back around the time the first iPhone came out. Yeah, it has been that long ago. The thing is, while the plans are “unlimted” you are only getting high speed data transfer rates up to a certain about of gigabytes per month. After you use that allotment of high speed data up, you are then throttled but not cut off or charged overages. Technically they are giving customers what they are promising, just in a rather backhanded kind of way. That was if you got in on a contract with pretty much all of the carriers. AT&T just announced that their GoPhone, prepaid plan, customers can now get “unlimited” data too."
