Hi, I ordered a Rokr E1 and get it now. In asia, the TF card coming with ROKR is 128M and i want to sell it and buy a 512M one. The problem is what does it contain in the card coming with the phone? Is it empty or with something? If i inset it into my phone and check the answer, the TF card will be looked like a used one and cannot sell in good price. So, Rokr users, please me. Thanks in advanced.
