I am on a family with 2 iPhones one for me and one for my dad. I going to be upgrading to iPhone 3G. How much more is it going to cost a month? I heard that the unlimited 3G is going to be $30 a month ($10 more than it is now). I am OK with resigning a contract for 2 years but is anything else going to go up? I have unlimited SMS is that going to stay the same price? Are the minutes going to stay the same price? Thanks.
