Yesterday, I purchased my Iphone from Digi. After that, I do it as usual by charge my phone for 8 hours. Besides, i also took out my Sim Card from Iphone(transfer contact). 8 hours later, i insert bck my Sim Card. But, i dono why, my phone keep cant read the SIm Card  . I keep take out n insert it by couple of times. Few times later, I tried to connect my Iphone with PC. While my iTunes read my phone, it pop up that said i hv to restore my phone to factory setting. So i just download the restore files from iTunes. When the download is done, i pressed the restore. While restoring, it pop out an error again which state that my phone cannot be restored becoz of error '23'. This time, i really worried about my phone...   How can this thing happen to me even i hvnt use the phone. I got class today till 3pm bt the Digi Centre just open till 1pm (coz saturday). Now i really nid  Lyn member teach or tell me what should i do or what i hv done it wrong? Or i just take it to Digi dealer?
