The new AT&T Wireless pricing plans are out for iPhone and iPad users and they're not really going to benefit the heavy user. As a matter of fact the pricing plans are typical AT&T. Somewhat confusing.
The big issue that will cause a flap is the up-charge for tethering. They want to charge you more for it, but so far, it's only on the iPhone. No up-charge for Nokia N & E Series phone users who have smartly chosen to use JoikuSpot and I haven't read where Android based phones on AT&T are paying more.
Somehow I am suspecting this is simply a starting point and overtime, tethering costs will hit everyone. My view though is tethering is a cost you don't need. First it drives down the battery life. Second it's sharing the bandwidth to the phone. I prefer to use MiFi's and in that case, Verizon's 3G or Sprint/Clear's 4G blows away what I've seen from AT&T.
Tether me not, for now.
P.S. No more unlimited data = no more unlimited calls via Skype.
