In case you haven’t heard, Instapaper quietly snuck its way into the Google Play Store today. I’m going to tell you a little bit about Instapaper, its significance to Android, and why this Android user won’t be buying it. Instapaper is a popular service for saving web pages for reading later. It not only saves pages for reading later, but also strips them down to a clean text-only format for easy reading.

It’s a nice concept, which when released back in 2008 for iOS, was original and extremely useful. But over the course of the last four years, Instapaper’s developer Marco Arment has spent most of his free time insulting Android and its fans… and now he wants us to give him money? Let’s take a brief look at the Instapaper app and its history to show just how insulting this is.

It’s been a busy day for photo sharing community 500px. They managed to launch a major update to their iPad app as well as release their first ever Android app. While Instagram is all the rage these days and has amateur mobile photographers giddy inside, 500px is a photo community built around passionate photographers and enthusiasts who discover, publish, share, buy and sell thousands of photographs every day. You won’t be snapping pictures with this app but you have the opportunity to:

Developers have already received several pre-release builds of Apple’s OS X Lion 10.7.3 software, and we had expected last week’s release to be the last one before the update goes public. But it seems there’s still some testing to be done. Apple has seeded yet another build to developers through the Mac Dec Center, this time with the build number 11D50.

Despite rumors that suggested its previous seed would be the last one before a public release, Apple has seeded another build of its OS X Lion 10.7.3 software to registered developers. The latest release sports the build number 11D46, and is available to download now from the Mac Dev Center.

After months and months of speculation, Apple will finally unveil its fifth-generation iPhone later today, but when will you be able to get your hands on it? According to one report, the iPhone 4S will launch in ten days, on October 14, and will start at around $99 for a 16GB model.

Apple’s unveiling of the fifth-generation iPhone now looks certain to be held on October 4, but how long will we have to wait until we can actually get our own sweaty mitts on the device? According to once report, the much-anticipated iPhone 5 will arrive in the U.S., Japan, and some parts of Europe around the middle of next month.

In typical Apple fashion, the company is keeping the release date for iOS 5 and the accompanying iCloud service a big secret, but the launch of these products could be right around the corner. According to screenshots taken from its internal RetailMe application, Apple has now begun training retail store staff for the upcoming release of its new services.

AT&T’s Vice President has reportedly confirmed to a number of the carrier’s employees that the iPhone 5 is “slated to launch in October,” and that it’s time to get ready for Apple’s fifth-generation device.

It’s increasingly beginning to look like that rumor claiming the iPhone 5 won’t launch until October was incorrect. Not only has Apple reportedly sent the fifth-generation device for carrier testing — a step taken only weeks before a scheduled launch — but according to DigiTimes, the company has ordered 10 million iPhone 5 units expected to begin shipping in September.
