What's the first thing you're going to do with your Motorola Xoom ? If you're Koush , the answer's clear -- install your very own ClockworkMod recovery image and ROM Manager, and grant the latter superuser permissions. That's right, on the very day of release, the Motorola Xoom's all but ready for custom builds of Android and all joy they bring.Meanwhile, Verizon's decided to bring us the latter half of the abruptly cut Xoom TV ad, which actually differs significantly depending on whether or not Spanish is your primary language. Either way, it's a fairly sordid affair, with no Iron Man feats of stratospheric skill to be found, merely a short demonstration of gaming with the accelerometer and a few quick swipes through Honeycomb. You'll still watch it if we tell you it's after the break though, won't you?
