Lumia 900 and Straight Talk

Anyone out there going for the Lumia off contract? Do you plan to use Straight Talk?

I've been with T-Mobile for over a decade and am ready to jump ship for the Lumia 900. AT&T's service prices are quite a shocker though. I have a friend using an unlocked Lumia 800 with Straight Talk and he is really happy with it.

I'm going to attempt this with the Lumia 900 and want to reach out to others doing the same. Do you plan to wait for an unlocked Lumia 900 (no AT&T logo!) or are you going to buy from AT&T off contract?
