Ive tried to unlock my 3510i phone by the codes I was given and seemed to have screwed it up, now when I try entering a code it says can not undo restriction, do I need to do a cable unlock on the phone now to fix it, if so, can I do this with the current data cable I have to transfer games etc accross to my phone, and what software is required. ?
ps. it still works on the original sim card
