T-Mobile is offering a sale on their HTC One S for $149.99 paired with a two year agreement. While the sale will be offered through the 21st of this month, I don’t see why T-Mobile doesn’t make it a permanent price drop. Considering AT&T’s higher spec’d HTC One X has already seen a permanent price drop to $99, the One S should be offered for at least that, or perhaps even lower considering it’s dubbed as “mid-tier.”
Either way, the One S still offers top of the line specs (minus the screen size and resolution) and appeals to many. Although keep in mind that T-Mobiles rumored HTC One X+ may be around the corner so you may want to save your upgrade until then.
