Wanting to get a 3G iPhone. If I pay the $30 data plan fee upfront for the 2 years ($720), will they give any discounts? Waive activation fee? Anyone know or have any experience with dealing with ATT with matters of this sort? Or does it just depend on if the CS rep is in a good mood! This may be the only way I can do this as the wife has a thing about monthly payments. I know, don't ask! Thanks.
