Want to check if you qualify for subsidized pricing for the iPhone 4S? Apple offers an easy online tool here on their website. Both Verizon and AT&T customers can use that link.
My subsidized pricing doesn’t kick in until November 19, that’s approximately 16 months after I bought the iPhone 4, which I pre-ordered and received on the day it became available in stores. Others may qualify earlier, as AT&T supposedly weighs in how much money you spend per month on text messaging and voice and data plans. I have the $30 unlimited data plan (grandfathered in), a $45 voice plan, and pay for unlimited texts.
