I have a Z1 and i switched out my hard drive and installed a new unlocked one with the 2010 maps Z3 update. I was wondering if anyone knows how to get the address book off the old drive and onto the new one. I guess i am looking for the files that need to be moved. I have both hard drives unlocked and are able to be attached to my computer. I am hoping that i can just move some files over to have my old address book on the new drive.
