I have a Nokia 5165 and been looking around on the web and found some codes I can put in my phone and work great like for example your voicemail. xxx-xxxxp#xxxxyour number p stands for Paluse Pound and passcode. Which is cool. ANother of mine I saw but dont sure how to use this very well. But I did enable Field Test and have a new screen on the phone. this code you enter is *3001#12345#. You will see NAM1, NAM2, SECURITY, EMERGENCY, SW VERSION, SERIAL NUMBER, PROGRAMMED, FIELD TEST. Can anyone show me some light on these items and if you know any new cool stuff that will be added let me know. IS there any other cool codes that you have and like to share as well. I like to get most out of this phone and as much as possible. Great phone never had a problem with it yet. Just want to have more menus added and more games added with putting in a few codes. Hope this gets some replays.
