I'm using Nokia 6230 cellphone. I would like to know that how can i remove my operator logo. I used to have a blank operator logo on my 6230 that worked fine, until one day i found when i turned off my phone and switched it back on it was no longer blank. The blank logo turned into a little question mark in a yellow box in the middle of the screen. So, can any body tell me that how to resolve o2 operator logo problem on Nokia 6230? Any body knows about it? Kindly help me out to resolve the above issue.
