I was all set to buy an iPhone today at an Apple store but now they say I have to pay a monthly data plan for an extra $30 a month. I thought I was going to be paying $79.99 for 900 minutes including that data stuff? Did I get the wrong info? When I checked into getting an iPhone a few months ago they never told me of this fee? So what does an average 900 minute plan phonebill come to with no extra text messaging?
