At Apple's press conference on Friday, Steve Jobs showed 3 phones that had the same antenna problems as the iPhone 4. This made Nokia and RIM retaliate to what Steve Jobs said about their phones. (Read here) But the third phone showed was the Droid Eris, and this had the most drastic drop of signal. It went straight from 4 bars all the way down to 0 bars.
HTC have not acted like Nokia and RIM to Apple's claims, but they have given a percentage of the people calling technical suport about the Droid Eris's antenna problem. Apple claimed that 0.55% of customers called AppleCare about the antenna issue but HTC is claiming that the Droid Eris technical support line received only 0.016% of people calling about the antenna issue. About thirty-four times lower than Apple's claim.
