T-Mobile USA has recently made available Facebook and Twitter applications for Sidekick users. Of course the apps only work on select Sidekick models — it’s for the owners of the Sidekick Slide, Sidekick 2008 and Sidekick LX, including Tony Hawk Sidekick LX.
Price wise, the Facebook app is completely free, whereas Twitter incurs a $2 monthly charge. That’s [Twitter price] for non-Sidekick LX users, only — if you own the LX, you’ll get to use Twitter for free, too!
