Kindle DX available from Amazon once again for $299

Well, it seemed like Amazon had finally moved on from its large-format Kindle DXe-reader last fall, but it turns out that was only a brief hiatus. As spotted by The Digital Reader late last month, the circa-2010 device is now available to order once again for $299. Amazon itself isn't offering much indication as to how long it will remain available this time, though, saying only in a statement that "our website lists the most up to date availability for all products," and adding that "we're excited to offer customers this option."

Google reverses course, makes CalDAV and CardDAV APIs open to all developers Mobile

Though Google chucked open API access to CalDAV back in March, it appears the company's had a change of heart. Up until today, only a select few whitelisted developers could make use of Google's calendar open standard; a decision it made based on actual usage data. But given the amount of feedback it's received from blocked devs in the time since, Google's decided to re-instate access to CalDAV APIs, in addition to those for CardDAV -- a first -- its open standard for contacts. The news won't make much difference for Windows Phone 8 users (CalDAV and CardDAV support was already promised), but at least your third-party apps can now continue to play nice with your social calendar.

Amazon Kindle for iOS gets line spacing options and multi-page highlights Mobile

Now that the summer book frenzy is in full swing, anything that helps us read a little faster is welcome -- so we're glad that Amazon just pushed out a relevant update to its Kindle app for iOS. The new 3.8 release adds line spacing options, so readers can fit more (or less) on to a page without tweaking the font. Those whose eyes demand an extra-large font can now pick one, too. Amazon is also laying some early groundwork for back-to-school with a focus on notation. It's at last possible to make highlights that span multiple pages, and Print Replica Textbooks gain filters for bookmarks, highlights and notes. Whether you're trying to get a jump on classes or just want to cram in one more novel during vacation, you'll want to swing by the App Store for the upgrade.

Huawei Ascend P6-U06 gets approved by FCC ahead of official release Mobile

The Huawei Ascend P6 hasn't been officially announced yet, but that's never stopped the Chinese company from leaking information like a faucet. It's unsurprising, then, that we'd notice the upcoming 6.18mm-thin device sneaking through the FCC database before the inevitable June 18th launch. Naturally, the docs are thin on details, but this particular version has a microSD slot and uses pentaband HSPA+ and quadband GSM / EDGE radios, so you'll have no problem using this aluminum-clad beaut in most parts of the world -- including the US on AT&T and T-Mobile. No LTE to report, sadly, but we'll just have to wait and see if any variants make its way through the federal agency as well.
