Reception problem with iPhone 4? Not really, says Apple. It's a mistake with the signal bars

Amidst class-action lawsuits over a faulty antenna, Apple said today that iPhone 4 users aren't really seeing a dramatic drop in signal strength when their hand covers the lower left corner of their phone. Instead, Apple now says that they made a mistake in their formula to calculate signal strength and the bars are overstating the strength — thereby leading to what appears to be a sharp drop. And they promised a software update soon to fix the problem. According to Apple, "the big drop in bars is because their high bars were never real in the first place."
