Also please note that you *DO* have to have a qualifying Verizon account. I asked and the minimum account you need is the $29.99 and you also need the $39.99 unlimited data plan addon. Too much IMHO. If you have the Imagio on another network (like I do) then here is a service which is in our pocket's reach...I submitted my IMEI and will post results as soon as I get my unlock code.
