Alongside the Nexus 4 and Nexus 10, Google has also announced a small update to the 7-inch Nexus 7 tablet. Called "Nexus 7 (32GB + Mobile)," it simply adds a pentaband HSPA+ radio and comes in a 32GB configuration for $299, a $50 premium over the 16GB model. It's available unlocked, but Google will be selling it with either a T-Mobile or AT&T SIM card pre-installed. It will be up to users to take the device to a carrier to get service — presumably using something like AT&T's Mobile Share plan. Just like the Nexus 4, the Nexus 7 + Mobile doesn't come with an option for LTE, no doubt a function of Google's strong desire to issue software updates without carrier intervention.

Other than the 32GB of storage and the radio, the specs on the tablet are the same as the version we've already seen, including the 1280 x 800 IPS display, Nvidia Tegra 3 processor, and 1.2-megapixel front-facing camera. Presumably it will ship with Android 4.2 out of the box. The Nexus 7 (32GB + Mobile) will be available on November 13th. As with the other Nexus devices, it will be sold via the Google Play Store, specifically in the US, UK, Australia, France, Germany, Spain, and Canada.

Update: Along with the new HSPA+ model, Google has revamped the pricing of the entire Nexus 7 line. The original 16GB model now costs $199, with a 32GB model — sans the cellular radio — coming in at $249. It's an aggressive line-up for Google, with the company now providing three different 7-inch options, all of which are cheaper than Apple's iPad mini.
