What a wild ride the Nexus 4 has been on. First, there was an insane storm that caused Google to cancel the announcement event. Then they announced it anyway, and there was unspeakable rage at the lack of LTE. But, it sold out in like 28 minutes or some similar number, so maybe people weren't really that mad after all. Then it was backordered for lots of people, and they were all mad again. But someone took it apart and found an LTE chip inside, which made everyone go hmmmmm. And now it (unofficially) has LTE support.
If you haven't heard by now, the Nexus 4 doesn't have LTE. It probably won't ever have it, either, based on what Andy Rubin told The Verge regarding the latest Nexus handset's network situation in an interview.
He talks a lot about "tactics" and "user experience" (read: battery life), but it really boils down to one issue: money. The fact that the unlocked 8GB version of the Nexus 4 is just $300 is absolutely crazy. Looking at the hardware, this is easily a $600 phone. Having used an Optimus G (the platform this phone is based on), I already know this is a truly premium device.
