If you have an AMEX that accrues MR points you can use the Membership Rewards Mall link to click through and buy the phones from the Apple store. It is currently paying 4x points, so you could get over 1,600 points for two 16GB phones.

The Apple store is under the office supplies category.

Once you have the MR points you can transfer them into DL and I believe AA, sometimes with a bonus multiplier.
