I'm just wondering if it matters where I buy the 3GS for a couple reasons. 1. If I buy at an AT&T store, can I return to an Apple store for replacement under the warranty or do I have to take it back to AT&T? 2. If I buy from the Apple store, will I still get my FAN discount on the iPhone data plan? Currently I have a $15 data plan added to my phone that was added by calling Premier, but I don't receive the discount. However, when I go to upgrade through the Premier website, it shows the data plan as $25.50 instead of $30 (15% discount) for the 3GS. So I just want to make sure I will be able to get a discount on the data plan as well, not just the service portion, if I get it at an Apple store.
