What rom are you using? CyanogenMod?

Ur build seems to be carrier lock. I think its korean telecom.
U need to be completely stock for latest updates.

I dont know much about it, just checked in setting> about phone...its showing android 2.2. I want to update it since long but I am not able to do it....

2.2.1 is froyo. Are you trying to root your phone or stock update ?

It is already rooted. I am trying to update, and even I am getting OTA update file but when I press on dowload and install but it goes off and turn back on. But once I get the x with unlock symbol then it goes off and never comes back on unless I remove the battery and put it back on. If I do it manually then I should get a triangle with exclamation mark in it according to forum but I never get that. I hope this information will help......thanks
