Google's Nexus 4 is very popular.
The smartphone constantly sells out and there's currently a 1-2 week ship time through Google's Play store.
T-Mobile is offering the device for a deep discount, $49 with a mail-in rebate and a contract agreement. We first heard of the sale on Tmo News.
The deal is good through Feb. 18.
T-Mobile is the only mobile carrier that sells the device, but you can buy it unlocked from Google starting at $299.
