Google’s Nexus 4, also known as the Optimus G’s younger LTE-less brother does pack LTE support under the hood, or at least some of the required components, although don’t expect Google to turn it on at any point in the future.

Google explained – or at least tried to offer a plausible explanation – as to why the handset lacks official LTE support, and LG also revealed why the device does contain at least some parts that make LTE work, albeit not all of them.

But intrepid Android hackers managed to get LTE working at least on some Canadian LTE bands, although that didn’t mean everyone in the world will be as lucky.

In fact, because LTE operates on different bands, depending on the spectrum available to a certain mobile operator, chances are that international Nexus 4 units will not get LTE support unless local networks use some of the same LTE bands available in Canada.

Moving back to North American Nexus 4 owners, we’ll tell you that some lucky AT&T subscribers will be able to access the carrier’s growing LTE network, at least in some U.S. regions where Band 4 is used (1700MHz).

So if you live anywhere in the following areas, you may be able to turn on LTE on your recently acquired Nexus 4, as long as AT&T uses it for LTE purposes: Phoenix, Raleigh, San Juan, Los Angeles, Las Vegas, Oklahoma City, Dallas, Chicago, Charlotte, Athens, GA and College Station, TX.

In case you live in any other AT&T LTE markets, then you’re probably using Band 17 (700MHz,) which isn’t compatible with the Nexus 4.

Let’s hear it from AT&T subscribers that got LTE running on their Nexus 4s. How is everything working out for you?
