What does that even mean? Google doesn't sell the Nexus 4 for $550 or anything close to that.

So does that mean LTE was officially activated or is that another marketing ploy?
In the meantime, it's been out of stock since day one here.
T-Mobile is moving toward clearer pricing plans that are more like the rest of the world and much more straightfoward:

For the lowest cost and most freedom, you can buy the Nexus 4 directly from Google or on Craigslist, eBay, etc.
(I'm not affiliated with T-Mobile in any way; I'm just a customer who buys a lot of Nexus phones)
I'm keeping my Verizon Galaxy Nexus for this reason. It may not be the latest and greatest, but it works really well and the data is really fast.

T-mobile is going to have to go to free-after-rebate to get customers.
The T-Mobile store salespeople do know this, and will tell the straight story which is that you'll save the most money if you buy the phone directly from Google and are willing to wait for it.
Or on a $35 (or more) plan for 2 years. Which will end up being $360 if you subtract the cost of the phone plan.
