iPhone 4 antenna better than iPhone 3G

Anandtech has done some tests on iPhone 4 antenna problem, and it seems better than the iPhone 3G problem that was found last year when iPhone 3G announced. Here's some conclusions that Anandtech has discovered through the tests

Holding the iPhone 4 without a case, in your left hand, crossing the black strip can result in a worst case drop of 24 dBm in signal. [...] The fact of the matter is that either the most sensitive region of the antenna should have an insulative coating, or everyone should use a case. For a company that uses style heavily as a selling point, the latter isn’t an option. And the former would require an unprecedented admission of fault on Apple’s part.

Another part:

iPhone 4 performs much better than the 3GS in situations where signal is very low, at -113 dBm (1 bar). Previously, dropping this low all but guaranteed that calls would drop, fail to be placed, and data would no longer be transacted at all. I can honestly say that I’ve never held onto so many calls and data simultaneously on 1 bar at -113 dBm as I have with the iPhone 4, so it’s readily apparent that the new baseband hardware is much more sensitive compared to what was in the 3GS. The difference is that reception is massively better on the iPhone 4 in actual use.
