It made your signal bars taller. No shit.
Basically, once upon a time Apple decided to deviate from the AT&T formula for how they represented signal strength on their phones. Apple's formula would possibly show five bars where a regular AT&T phone would only show three under the same conditions. iPhones weren't actually picking up a stronger signal, they were just misrepresenting it on the phone. At best it was a blunder and at worst it was a sort of fraud.
The iPhone 4 antenna problems led them to admit to this, as one of their early excuses was that iPhone 4 owners who were experiencing problems didn't actually have as strong a signal as they thought they had in the first place.
The update, and therefore the misrepresentation of signal strength was apparently present in earlier versions of iOS as well, and affects models clear back to the iPhone 3G.
The update doesn't actually affect your reception or real signal strength. Your phone should still work in all the same places it has before (or not work in all the same places, as it were). You just won't be led to believe you have five bars of signal now when AT&T's standards would say you only have three.
