My iPhone has gone again. Error 1015 was displayed and I was not able to avoid it and fix my iPhone. It's not good. I wanna use it. So I am thinking to buy new one, but it is expensive. Do you know how much it costs? If you want SIM free model, about 80,000 yen. Too high to pay for me now! We can buy used one in some shop. It is often 3G or 3GS and costs more than 30,000 yen. Or, Softbank sells them cheaper, with some limitation. It's not bad but I haven't use my phone over 2 years, so I don't have so much advantage. What should I do?
