Field Day: iOS 4.3 Beta Brings Back Full Field Test

Good news for iPhone users who want to check their signal strength: Beta 3 of iOS 4.3 has reintroduced the field test mode that disappeared in the wake of the "AntennaGate"/"Death Grip" fiasco.

If you're running the current beta, dial *3001#12345#* and hit Call.  You'll get the above screen.  Notice how the signal bars in the upper left corner have been replaced by a negative number?  The smaller (i.e. less negative) the number is, the lousier your signal is.  In other words, a reading of -79 would be a worse signal than the -104 shown here.

The field test returned in an abbreviated form in iOS 4.1, but now it appears to be back in full force.
