I was running around on old forums i rarely check now-a-days (crackberry, tipb) and i stumbled upon a pretty cool thread. (it was actually pretty old 2008 or early 09)
They figured out a code to input that changes your 5 bars of signal to actual dBM. I found this Intriguing since most of the time people say the bars are a vague description of what is actually going on.
So i booted up my 9700 and 9000 to give it a try. It worked of course, but since i no longer use a BB i was wondering if there is a way to do it on a Pre Plus.
