Will a bionic work on 3G? I am looking at changing from my droid x to a bionic but I don't want to change plans with verizon(since I have an umlimited data plan). Do I have to have a sim card for the bionic to work on 3G? Can I get a bionic (whether refurbished or used) and set it up on my account on the verizon website? When I switched to the droid x, I made the changes thru my account on the verizon website so I was wondering if I could do the same with a bionic as long as I didn't want 4g and sim card?
