second dilema:
i tried to unlock my phone so i cud use my sim card,i did all the steps n used the polaris programme.after finishing the operation a msg appeared to tell me that im already sim unlocked,but wen i insert my SIM it still tells me to write a code,SO IT IS NOT WORKING.

A PROBLEM HAS OCCURED WHILE OPENING THE SHORTCUT OR WHILE LUKING FOR THE FILE DEVICE.

Dude its asking for your Sim pin and not Network lock Code....
Every New or old sim usually has a 4 digit code.. which can be changed n disabled from phone. you phone is sim unlocked which means .. u can use any service provider sim in it. but u need to know ur sim code... if you have lost it..then u can go the ur service provider and say that u have lost ur sim and they will give you a new sim with same no. and then you can use that..

hope this helps..
