Setting up Blackberry without “3G Only” Network Mode

Warning : You do this at your “Own Risk”
Read Question :

When I perform a network scan in my area and then select to connect to the 3G network from the list of networks. There is no “network mode” option only to “3G”. How can I force it to connect to 3G?

The only network mode options are:

“2G”

“2G or 3G”

Solutions :
A tool to provide you with an engineering screen unlock code.
