Hi there, i was looking for some answers for my problem but i readed your thread and seems interesting.
I have a Nokia 3586, and i did the "network monitor" thing, i don't know what these nimbers are but the refresh rate is about 2-3 sec. Other thing is that... as I have understand... the difference between my phone 3586 and your 3586i os that your phone has an gps localizatiom module that can be activated/deactivated. you can see it here http://www.nokiausa.com/phones/3586i
I was playing with these codes that were posted here. I have NO idea how I did it, but my phone now says "Searching for Service" and will not work. Does anyone know how to undo what I may have done, even though I'm not sure what I did. Also my provider is MetroPCS, if I call them are they gonna be upset if I tell them what I've done, or should I just say that my phone started saying "searching for service" and I have no idea why? Thank You for any help you can give me!
