Last month HTC announced the SIM and bootloader unlocked Developer Edition of its new One would be available at the same time as regular carrier versions, and it's held to that promise. Tonight it tweeted pre-orders will begin the morning of April 5th at 7AM PT / 10AM ET, a day after AT&T's list opened and the same day as Sprint. While there was no mention of ship or regular sale date, Android and Me reports being told by company reps at today's Facebook event that sales will begin April 19th. S
