iPhoneRoot performed iPhone research for Wall Street Journal

Last week our site iPhoneRoot.com was contacted by Wall Street Journal journalist to comment on recent iPhone antenna and signal issues. We certainly shared our thoughts. After interesting conversation we agreed to perform a research of the latest iPhone iOS 4 firmware. As a result WSJ published two interesting articles covering iPhone, antennas, signals and bars. Take a look:

• Hidden Formulas Send Mixed Signals on Cellphones
• The Case of Apple and the Mysterious Bars

We will soon post detailed data from our research.
