T-Mobile’s warning their employees that stock of the T-Mobile SideKick 4G will be limited directly after launch and to direct their customers that they’ll have a lot more two weeks afterward. It’s a usual tactic used not only by carriers, but retailers and OEMs to “test the waters”, if you will. They don’t want to order more than they can actually sell. And the hesitance is understandable considering the SideKick brand was once near death but brought back to life thanks to Android. We’ll see if the new device can live up to the standards the old line of Danger-based SideKick devices set. [via TmoNews]
