It's Nokia X3-02 touch? or whether Touch & type? or Type? You can specify that also,!!then country and Network it restricted now?
If your Nokia mobile phone displays Phone Restricted with an Undo option and selecting Undo results in an Enter Restriction Code error, your Nokia mobile phone is Network Locked. This means your Nokia mobile phone has been restricted for use on one specific network and a Restriction Code or Unlock Code must be entered before the phone can be used with alternative networks.
If i need to compare out of Nokia 5800 and E72, i definitely go for E72. You could type it much better than 5800. I always feel typing on Qwerty pads are much better than typing on Touch Screen. Also, regular use of 5800 for Chat, Typing, Games would result in More wear and tear of Touch Screen and i hate spending on touch screen after every year.
As the message had said it is corrupted, and it is realy corrupted.
The database of your phone is damaged.....could be by a virus or other anomalies.
And you nothing to do with it by yoursef, it is really complicated if you do it by your own, specialy if you don't have the necessary tools for it, The better thing to do is to contact a specialist near you. Or you can contact one of the repairmans in this site, you knows........one of them is residing next to you. Tnx! A rate from you wi be much appreciated........
