I just bought a new-in-the-box HP Pre 3 for Verizon on eBay. I'm not tech-savvy, so I took it to the Verizon store to have the contacts transferred from my old Palm Pre and to have to have the new Pre 3 activated. After messing with the phone for about 45 minutes, the technician said she could not activate it without knowing the passcode. If the seller does not know (or send me) the passcode, is there a way to activate the phone without it? Thanks!
