Returning iPhone 3G... subsidized replacement?

Hey guys... I mentioned this in the AT&T forums but I think I'll get a quicker response here 🙂

So I heard, if the rumors are correct, that AT&T will have the Blackberry Bold sometime next month. I'm still on the fence with this iPhone... only had it since Wednesday... so 50/50 with it.

If I return my iPhone 3G (before the 30-day period of course) to the Apple Store, get my refund with service line still active... can I go to AT&T with proof of return and pick up a Blackberry Bold for $299 subsidized (or any phone for that matter)?

Or...

Would I need to return my iPhone to the Apple Store, get a refund, cancel my line (no ETF within 30 days)... then sign-up brand new with AT&T for the for subsidized pricing.

Thanks in advance!

YEP. A lot of people have lost interest due to all the delays.

Not really an iPhone killer (there is no such thing 🙄)... IMO, Blackberry and iPhone are in two different leagues.
