To do check Apple iPhone’s Signal Strength in iOS 4.1, we only need to call this number *3001#12345#* and hit call button. And your signal bar will be change like this one. To switch back you only need to hit quit button / big button on the bottom of your screen. My Digital Life said, this function only work on iPhone 3G/3GS/4 and must be on iOS 4.1, maybe on iOS 4.2 will be made more details and comprehensive field test measurements.
