For those who returned their Verizon for the TM Tab... I will need to buy a TM from online. I have a VZW mifi, With the TM Tab is there an activiation screen? Or does it need to be unlocked the way my VZW did? How do I buy pass the activation screen? So until I set up a plan with TM, i won't have IM capability, anything else I should consider? I guess the data plan I have with my VZW Mifi will not work with the TM Tab, right?
