Google’s new Nexus 4 has been a hugely popular device since it first made its debut back in November, but the apparent supply issues surrounding the Galaxy Nexus successor have been well documented. Many would-be customers have been unable to snap up the device due to the short supply, while those who have have been forced to wait up to six weeks for their handset to arrive from Google Play.

What isn’t clear is why the Nexus 4 is so hard to get hold of. Some reports have speculated that LG simply cannot produce enough to meet the overwhelming demand, while others claim Google just didn’t order enough in the first place. So what is the truth behind the Nexus 4? Cathy Robin, director of LG France’s Mobile Communication division, has revealed all.

The Google Nexus 7 is now available to purchase with a T-Mobile data plan through Google Play. The device is priced at $299 — the same as AT&T’s HSPA+ model — which makes it just $50 more expensive than the Wi-Fi only model. T-Mobile has also announced that it will be expanding the availability of Google’s hugely popular Nexus 4 handset.

LG has received a lot of criticism for its Nexus 4 production rates in recent months. Since the handset went on sale last November, it’s been incredibly difficult to get hold of for the vast majority of would-be customers. Google Play stock doesn’t appear to be getting replenished as often as it should, and when it does, it’s sold out within just a few hours.

From LG’s point of view, however, Nexus 4 production is proceeding exactly how it was planned. The Korean company denies there is a supply issue, leading many to question how many handsets Google actually ordered.

Google has begun rolling out its latest Android 4.2.2 Jelly Bean upgrade to the LG Nexus 4. The software is currently reaching handsets located in Brazil and Malaysia, according to reports, but it’s likely it will also appear in other countries relatively quickly. Unlike Android updates for third-party handsets, Google’s don’t have to go through carrier testing.

So, you’ve upgraded to the LG Nexus 4 and you have an old Samsung Galaxy Nexus kicking around that you no longer have a use for. You could sell it — the device still does well on eBay, despite being more than a year old — or you could hold onto it until late February when you’ll be able to get your first taste of Canonical’s brand new Ubuntu platform for smartphones.

Announced at CES 2013 in Las Vegas this week, Ubuntu for smartphones is coming to do battle with Android and iOS, and its first image will be for the Galaxy Nexus.
