To get back to normal mode after I had resprung with the dB I had to reset all settings, bit of a pain in the backside to put things back but got rid of the dB

Yup, reset all settings. That was the only way that I could bring the bars back.

Thanks, when I reset all settings the bars returned. It sure is a pain to redo all settings for such a simple thing. It would be nice if Apple made it switchable in the field test screen.
 
I just upgraded to 4.1 this afternoon and decided to do the Field test. At home were I have barely 3 bars I got between -102 and -94, without moving an inch. I did the death grip on the phone and it went to -111 then came back to -109.

Now I believe that this is measuring in decibels and if I remember my Navy Radar Antenna electronics correctly for every 3 DB rise your power doubles. Is this correct on cell phones also?

This would mean that my signal doubled from -111 to -109.
 
Is there a way to get the -db to stay instead of the bars? Once I exit field test mode the -db stays for a second then switches back to bars, but I would like to keep the -db. Thanks in advance.

^My question?
 
I just answered this question on another thread about 2 hours ago

Thanks.


1. Go into Test Field Mode
2. Press and Hold the Sleep/Wake button until you get the 'Slide to Power Off' (then let go)
3. Press and Hold the Home Button for about 5-10 seconds (this will re-spring your springboard)
4. Now tap the bars and it will be replaced with the -db, tap again to bring back the bars. (Warning: the only way to get rid of this method is to 'Reset All Settings")
 
The bars/numbers indicate signal strength. The closer it is to -50, the better the signal strength.

will having my phone in field test mode and the db showing void any warranty? Like if i have a issue and bring to genius bar and they see this wil they be like VOID!!!!!! :eek:

No, this will not void the warranty at all, so don't worry about it.
