Hi all!
Just wanted to throw in a quick tip for those of you who's not aware of this.
To check your networks signal in a more accurate way, to check if it's the
signal strenght that's bugging you, you can always use the iPhone Field Test.
Just open the phone app, then the keyboard and type in:
*3001#12345#*
and then hit call. You'll now bring up the iPhone Field Test screen, which
has a lot of information that I have yet to figure out. But the handy part,
is that the bars that shows the signal strength on the left side of the
status bar, has now changed to a number, with a minus sign in front of it.
This is a much more accurate number than the 5 bars can give you, and you can
also use it when calling your carrier to complain!
Here's how it works:
The lower the number, the better is your signal. You'll never get anything
lower than -40, and that's the theoretical signal you may get when standing
right beside a network base station. But considering that 5 bars is equal to
around -80, you can get much more information from this.
I think 2 bars is somewhere around -100, and above -100 you will find that
your voice begins dropping out and making wierd noises while on a phone call.
-110 is the place where the whole phone calls starts dropping out and you'll
have to constantly try to call your conversation partner back, even though
you'd probably not have any good luck doing that.
At around -120 - -130 the network announced will fall out, and "No service"
will appear in stead in the status bar.
That's it, a lot more accurate information to get from this hidden iPhone
feature than the common signal bars.
Oh, and a last tip:
If you want this to stick in your status bar, so that you can always switch
between signal strength in bars or this number, which I believe is given in
dBm's, you can do this:
While the Field test screen is open, hold down the Sleep/On/Off-button until
the slide to turn off appears. Then, don't slide to turn off the phone, but
hold the home-button down for a few seconds, to force quit the field test
app, and return to the home-screen again.
Now you can double-tap the area in the statusbar where the signal strength is
shown to switch between this dbm-number and the more common known bars.
