When i receive a text message it comes up with a international area code is in front of the number , the text does not show me who it is from my contact list, can i change the setting so it does not display this.

I did get told to install

add i.unlock.no
to installer sources then install Phone # to name fix
it will ask whats the longest number put 11

So i did but it says only for version 1.1.1 and i have version 1.1.4 will it do any thing to the phone ???? or fix the issue i have .
