Music streaming service Spotify has announced that it will continue offering unlimited listening to its free customers in the United States. In case you didn’t know, all that free music you’ve been listening to won’t last forever. Spotify said from the very beginning that free users would only have unlimited listening for 6 months, and it’s been 9 months since the streaming service went stateside. Looks like the honeymoon will last a little longer.

A specific date for the unlimited listening discontinuation has not been given, so you may want to think about coughing up $10 per month for a Spotify Premium account. There’s also some good news for certain Spotify users in Europe.

If you visit www.instagr.am/android you’ll be greeted by the above sign-up form. That’s right, Instagram has started letting users sign up to be “the first in line” for its official Android app. No details about the app or its release date have been given at this time, but the launch is definitely on the near horizon.

We told you that Instagram was coming to Android last week, adding that the app’s co-founder believes the upcoming Android version is “better than the iPhone app” in some ways.

How will the two apps stack up? We’ll let you be the judge!

Instagram is one of the most wildly successful apps to ever hit the iOS App Store. The app’s co-founder, Kevin Systrom, recently revealed that Instagram now boasts 27 million active users on the iPhone alone during the South by Southwest conference (SXSW) in Austin, Texas.

We’ve all been clamoring for the popular social photography app to make its way to Android for many months, and it has been confirmed that Instagram for Android is coming “very soon.” The app is currently being tested in private beta.

The boldest claim Systrom made was that Instagram for Android is, in some ways, “better than our iPhone app.”

The iPhone is ranked as the top smartphone in the United States, and with sales on the upward trend worldwide, one would think that there’s no stopping Apple’s magical handset. As it turns out, the iPhone has a “crutch” that’s key to its success: carrier subsidies.

It’s common practice for U.S. carriers to subsidize a phone to make it more affordable for the average consumer. The trick is that customers get locked into a two-year contract. While Apple profits and carriers take an initial hit off the subsidized model in countries like the U.S. and U.K., less expensive Android devices are dominating markets where consumers pay full price for their new phones.

Whale Trail is a popular sidescroller that originated from the Apple App Store. The game can best be described as Tiny Wings meets Angry Birds on acid. Whale Trail is a colorful, charming, quirky and addictive game — not to mention one of my personal favorites.

As we’ve already told you, Whale Trail recently launched on the Android Marketplace. I got to sit down with the head of the company behind Whale Trail to talk about the pros and cons between developing for Android and iOS.
