iOS 4.0.1 Update, Signal Bar Fix. iPhone 4 Antenna Internal Fix Coming?

Remember a couple of weeks ago when Apple said they were “surprised” to find that the formula they used to calculate reception bars was faulty and “in many instances, mistakenly displays 2 more bars than it should for a given signal strength”? While I remain skeptical that this was truly a surprise to Apple, it appears that they’ve adjusted their formula with the new iOS 4.0.1 update.
I haven’t lost any bars yet, but apparently I live on top of a cell tower. What I did notice is that Apple’s signal bars have become taller. So while you may soon get hit with the reality that your three bars are really one bar, you can at least take comfort in the fact that it’s represented by a taller bar.
In semi-related news, Apple will be holding a press conference tomorrow, most likely about the iPhone 4′s antenna woes. Could this be related to a report from TheStreet that the problem is related to an internal insulator and an internal “bumper” fix may be coming? It’s an enticing thought for those of us who love our iPhone 4s, but fear the consequences of touching them inappropriately.
