Nokia Operator Logo - Solution

The Nokia phones that support color operator logos may not allow to assign the operator logo from the gallery. To get a logo, you have to browse using GPRS. A picture is considered a logo if its content type is image/vnd.nok-oplogo-color. Here is how to bring an arbitrary file into your phone as an operator logo if you have access to an HTTP server that supports CGI scripts:

• upload a picture to the server (sample file name is logo.gif)
• save the following shell script into a file with a name that ends with .cgi, e.g. get.cgi
  

  #!/bin/sh
  echo "Content-Type: image/vnd.nok-oplogo-color"
  echo ""
  cat logo.gif
  exit 0
  

• make the file get.cgi executable
• browse to get.cgi with your phone
• In the "Settings-Display Settings-Operator logo" menu, select "On"
• Go to the main screen
• If you do not see the logo, then turn your phone off and back on
• If you do not see the logo, then your provider does not officially support user-defined logos; the only chance to see it is the signal is weak when you turn on the phone, but even that is not guaranteed. I only saw the logo I have downloaded into my phone twice, and both times for a very short period.
