ATT charged me 8.25% tax (in California) for my 8GB iPhone, and the tax was computed on the pre-subsidized amount which is $399. So my final cost after tax turned out to be $199 + $32.92 (8.25% of $399) = $231.92. Did others who bought the phone from AT&T get taxed on the higher amount as well? What about those who bought it at the Apple store? Shouldn't AT&T charge sales tax on the lower amount?
