So you pay $40 for your iPhone contract, with data, all inclusive. Care to provide a link? I'm sure a lot of people would be interested.
For a comparison, the cheapest iPhone 4S plan is Sprint for $70/month + $200 with a 2-year contract.
$70 x 24 months, + $200 =
$1880
Unlocked 16gb 4S is $649. T-Mobile basic data + voice is $30/month.
$30 x 24 months, + $649 =
$1369
You just saved
$511, plus you have the freedom to change plans and providers whenever you choose, and you can travel with your phone.
But please, don't let facts and basic math stop you from spouting off yet again.
