    On the new iPhone to make it thinner apple had to save space, they decided to put the antennas round the outside of the phone and use them as the sides rather than keeping them inside like on the previous iPhones.

    So the edges of the phone look like this.

    When you touch the side of the iPhone some of the antennas energy is lost as heat (because your hands are hotter than the phone), which makes the antenna less efficient.

    A recent study by Aalborg University suggested that by holding the antenna in your hand could reduce the signal by more than 90%.

    What have Apple said?
    There's nothing wrong with the phone, its just the bars are been displayed wrong.

    Does this cause interference with calls?
    Yes. http://www.youtube.com/watch?v=03PQyWp0mWE

    Does this cause interference with data?
    Yes. http://www.youtube.com/watch?v=kYmVpoccPnc

    Can this be fixed by a software update from Apple?
    Apple seems to think it can, although I'm not sure how if its a hardware problem.

    So what does everyone think Apples going to do about it?

    What's your source? That information just looks wrong.

    After the news starts bashing the iPhone for that, Apple will probably replace them.

    That, or suggest buying a case or Bumper.

    Heat is a form of energy. Energy fundamentally travels from highest concentration to lowest concentration. Therefore, if your hands are hotter than the phone heat would not travel from antenna to hand, but from hand to antenna (which by your logic would boost the signal strength).

    Even if his logic is flawed the iPhone 4 definitely seems to be having some issues with the service.

    Yeh, the issue is only when you connect the 2 antennas by holding it in a certain way, still a big problem, but nothing to do with heat or anything...

    Oh, I'm aware, I just feel like if you are going to "explain" something you should get your facts straight. I'm not entirely ready to concede that it is a software only issue, but I'm willing to give Apple to benefit of the doubt. The backlash for promising a fix only to not deliver one would be far greater than admitting the mistake in the first place, especially straight from the mouth of Jobs.

    Has anyone tried turning off wi-fi and bluetooth and connecting both with your hand? Without using an app that uses GPS of course.

    Maybe during a phone call they (Apple in a future update) will turn off the wi-fi, gps and bluetooth in future updates, unless your using hands free in which case you probably aren't holding it, makes sense right if the two antennas touching theory is true. Speaker phone could be an issue...

    Even when things are hardware problems you can sometimes find away around it with the software
