OP - You also have to keep in mind the disparity in plan rates for what you'll need with either phone. With Sprint, you get $99/month for EVERYTHING unlimited (less if you can wrangle a discount out somewhere, EVPDiscount's basic rate drops 15% off your bill, if you qualify) AT&T charges $130 for the same plan. Multiply that times a two year contract, and you just tacked on $720 to the price of your "cheaper" iPhone.

So to recap:

iPhone: $99 for a REFURB plus $720 in increased plan costs = $819 for your phone
T Pro2: $599 MINUS a heavy discount for the same two year contract (best estimates I've heard are $249-$349 on contract) plus a cheaper rate plan.

Seems like a no brainer to me.

Tack on the fact that I detest Apple's elitist policies and it really TRULY becomes no choice at all for me.

I just wish Sprint would get off their rumps and release the damn thing already.
