The iPhone 4 Redux: Analyzing Apple's iOS 4.0.1 Signal Fix & Antenna Issue
by Brian Klug & Anand Lal Shimpi on 7/15/2010 12:28:00 PM
In case you haven't noticed, the iPhone 4's antenna design has come
under considerable scrutiny. In our iPhone 4 review, we investigated
the iPhone 4 antenna and came to two conclusions. First, that iOS 4
was displaying signal bars in an overly optimistic manner,
compressing the dynamic range of possible signal bars users can see.
Second, we identified a worst case signal drop of around 24 dBm when
the iPhone 4 is cupped tightly in the left hand, covering the black
strip and possibly detuning the antennas and adding additional
attenuation from the presence of the hand.
Since those initial measurements, we've been working tirelessly to
both characterize the problem, fully understand the mechanisms behind
it, and report on a number of possible solutions.

Even Without iPhone, Verizon Is Gaining on AT&T
By BRAD STONE and JENNA WORTHAM
July 14, 2010
It is a question that the nation's early adopters keep hearing from
friends: when is the iPhone coming to Verizon?
The combination of the biggest cellphone carrier in the United States
and Apple's smash-hit phone would certainly be a powerful one. And it
would be a major challenge to AT&T, which has been the exclusive
carrier for the phone since its debut in 2007.
But Verizon could decide that it does not actually need the iPhone,
thanks to its deepening ties with Google.
In big cities, AT&T's network has buckled under the data-heavy
demands of the iPhone, frustrating customers. Verizon has managed to
avoid similar problems while working with Google, Apple's latest
nemesis, to offer several strong rivals to the iPhone that use the
Android operating system from Google.
On Thursday, Verizon will begin selling the Droid X, an Android phone
that many say may be the fiercest challenge yet to the iPhone, Steven
P. Jobs's crowning creation.

Yet, they are now advertising two-way video with your S.O. or friend.
Seems like they should also mention that isn't going to work except when
both phones are connected via broadband WiFi.
