If you're not familiar with PrivacyStar, they offer a complete solution for call blocking, text blocking, call lookup and even caller ID on Android devices. The app offers a free 7 day trial in the Android Market but not wanting to leave anyone out of their celebrations, they've offered up some free PrivacyStar licenses to Android Central readers.
If you're looking to win one of the four licenses available just drop a comment here and we'll pick some winners for Monday, until then -- you can jump on past the break for the full press release as well as a link to the 7-day free trial of PrivacyStar.
