Here at WPCentral, we're pretty big fans of Nextgen Reader which is billed as "the fastest Google Reader client around" (we tend to agree). That's why we're excited to team up with the developer, NextGsoft, to give it away to all of you for $0 for the next 36 hours.

That's right, normally this highly rated app fetches for a $1.99, but for the next day and a half you can get it for nothing at all. The app hit v2.0 back in September with Mango support (see our video review) and since then it has received numerous updates, including version 2.4 which just went live in the Marketplace today. That version brings a bunch of new features and fixes to the table:

• Live tiles now support images.
• New manage sources hub with search, add, rename and delete feeds/folder.
• Improved scrolling in article view.
• Pin tiles easily to start screen from manage sources hub.
• Added change password/account option.
• Improved sharing page.
• Bug fix: save post title in read it later.
• Bug fix: support for Japanese font.
• Bug fix: better support for multiple YouTube videos in article.
• Many other improvements and bug fixes.

So how do you get the app for not a single penny? You just have to do the following steps to get an unlock code:

1. reTweet this story and/or follow Nextgen Reader on Twitter (or both!)
2. OR do the "Like" thing on Facebook
3. THEN Fill out this form for your registration key and you're good to go (the key will be emailed to you within the week which will unlock the Trial)

From WPCentral and NextGsoft, enjoy your free Google RSS client! Grab the trial of Nextgen Reader version 2.4 here in the Marketplace and read more at the Nextgen Reader site for details on the update.
