Can someone please help me with my 7250i software? I have bought a USB data cable, not the original. The cable comes with a trial oxygen software, but it don't work properly with the i series. I can see the ringtones did transfer on to the phone on my computer but in fact it is not actually on the phone. I am hopeing someone can help me with this problem. I can read chinese but can't write on my pc. Many Thanks in advance
