Does anyone know if there will be any unsigned apps on the captivate for AT&T? App sideloading? Or is ATT gonna lock this one down like the Aria and Backflip? Engadget preview said: "happy to see AT&T hasn't done much to the OS" "AT&T may have been accused of crippling its Android phones, but the Samsung Captivate -- one of the US versions of the Galaxy S -- is about to change all of that." But they don't mention whether or not they've disabled app sideloading and unsigned apps. Any clues?
