Hello all, I am new here and my only experience with the droid so far is fixing my wife's DX when she messes it up. I currently have a blackberry Tour <gasp> that I hate immensely. I am due for an upgrade and want a droid. The Bionic seems like my next phone. I was reading on it all morning an noticed that a locked/unlocked bootloader was mentioned several times. What exactly is a bootloader?
