Boys and Girls Thank The Gizmodo:
Richard Baguley, chief cellular ninja over at WirelessInfo.com, just
published a number that, when called, turns your iPhone into a mobile field testing
station. Suddenly, up pops a new menu (as you can see on our own iPhone at left)
that provides detailed reporting on strengths and characteristics of the cell
towers in your area, plus a load of other nerdy networky factoids. In other
words, you can see things that AT&T might not want you to
see.
What's cool is that you can even enter field test mode during a
call just by tapping the iPhone's "Add Call" icon, then the field test number.
But before I give you this magic number, it is my duty to share Richard's
warning.NOTE: Although it seems that most of the information is read-only
(so you can't change anything), field modes like this have the potential to
damage your phone and possibly interfere with the phone network. We are
providing this information as-is; we cannot be held responsible if anything you
do in this field mode damages your phone or the phone network.There, now that the warning is out of the way, here you
go:*3001#12345#*
Dial that, and have fun fiddling. If you do discover anything
freaky, please report back to us, and, of course, to Richard. If you whack out
your iPhone in the process, don't come crying to me
