This is just a heads up that a similar deal to one we covered earlier this month has popped up on 1 Sale A Day again. The Lumia 900 is listed for $220, which is an absolute bargain for a decent smartphone. While it may be refurbished (certified by AT&T), it'll still provide a rich user experience especially with the Windows Phone 7.8 update rolling out.
1 year manufacturer warranty is included in the deal. If you're interested in picking one up, be sure to act soon as there's only 14 hours remaining at the time of writing.
