If you haven’t yet entered our Share the iPad Guide Giveaway, this weekend is your last chance to do so. To celebrate the release of The iPad Buyers’ Guide + Free iPod/iPhone Book 5, iLounge is offering our readers a chance to win some great prizes for sharing the Book with friends, family, and social network followers. To enter, simply retweet this message—complete with bit.ly link—to your followers. 50 retweeters will be selected at random to win CandyShell cases from Speck, while four additional readers will be selected based on the positive influence of their tweets to receive either one of three second-place prizes—iHome iA5 App-Enhanced Alarm Clocks—or the grand prize, an iHome iP1 Studio Series Speaker System. Our Share the iPad Guide Contest ends on June 15, 2010 at 11:59PM Pacific Time; more information, including official rules, is available on the contest page. Thanks, and good luck!
