Slow lane: why Google's new Nexus 4 doesn't have LTE | The Verge
Google may be getting serious about selling hardware with the Nexus 4, but not so serious that it's willing to compromise with carriers, and compromising with carriers is the only way to make LTE work.
And there's precious little to suggest working with carriers is even in Google's best interests, or in the best interests of Nexus customers. The Galaxy Nexus was announced last year with a promised LTE version on Verizon, but the carrier held back releasing the phone for months to promote its own Droid RAZR instead. Google eventually grew tired of waiting and sent unlocked HSPA+ devices to reviewers. And software updates for Nexus phones sold through carriers have been problematic as well: it took the Verizon three full months to disseminate the Android 4.1 Jelly Bean update to its Galaxy Nexus, slightly longer than Sprint. That's actually better than it used to be with carrier-partnered Nexus devices, but still much longer what Google can achieve without carrier intervention ? and far too long in a marketplace where Apple has set a standard for simultaneous worldwide software distribution across multiple carriers.
...that means that the Nexus 4 will only be available as an unlocked HSPA+ device.
