you can try unlocking your phone through codes. its the safe way to unlock your phone. because when you unlock your phone through software or hardware there are possibilities for data getting corrupted or lost. but there is no such possibilities when you unlock through codes. thats y i prefer this method to unlock my phone. i got the codes from this site Unlocking4U.com to unlock my phone.
