File this one under pure speculation for the time being, but all indications point to a T-Mobile Sidekick release party on the horizon. DJ AM, a veteran of Sidekick II and Sidekick 3 release parties, has a private T-Mobile event listed on his official MySpace profile. The date, October 16th, is in line with out mid-Fall new model expectations. If the event is indeed legit, the only question remaining is whether T-Mobile will be dropping the Sidekick Slide or the Sidekick LX. Stay tuned for more info as it becomes available, and keep your dials tuned to the Master P Sidekick Hour, debuting soon on a Clear Channel station near you! If you had to guess, what model (or both) do you think they’re launching if this rumor pans out?
