I just turned on my Xbox 360 and what do I see but a giant Sidekick LX 2009 3G staring back at me! T-Mobile is teaming up with Microsoft for a special Sidekick promo on Xbox Live. If you download the T-Mobile Gamer Picture you’ll be entered in a contest to win a free Xbox Live Gold membership. In addition, the weekend of August 29th-31st will be a free Gold Weekend. That means that any Xbox Live Silver members will have all the privileges of Gold accounts for the weekend.
