I pre-ordered the iPhone 4 within minutes of Apple and AT&T's pre-order launch sites. I tried Apple first, but after many failed attempts I resorted to the AT&T website. Ordering went smoothly with no errors. On the 22nd of June, AT&T charged me $199.00, but that was it. Tax, according to the invoice was around $70+ dollars, but it wasn't part of the charge. The next day, the phone arrived and to my surprise, it came a day earlier. It's been 2 months and I've yet to get billed for the tax on the phone. Anyone experiencing this?
