Not sure if this has been covered but I thought I read a few articles before the release of the 3GS that AT&T was going to lower the cost of the IPhone data plan. I think they should lower it down to $20 a month, then I wouldnt mind paying the extra $10 a month for the AT&T Navigator. Honestly though I think the only time they will drop the price (if they ever do) is when their exclusivity period is up and the iPhone is available on other carriers.
