    Hi Dave,

    Great to hear another NZer mentioned, and by Cringely himself! A recent Cranky Geeks (with John C Dvorak) had a shout out to NZ 🙂

    As someone DESPERATE to import an iPhone 4, I enjoy reading all I can about these “antenna issues”.

    Do you think they will manifest badly in New Zealand? I have an unlocked Original iPhone, I rarely make calls or send texts, but obviously…having a phone that can make PHONE CALLS is important for emergencies!

    I managed to get an iPad a month or so ago, but this wait for the iPhone 4 is just as tragic! I’m going to try and pressure an English friend into sending me one soon!

    Thank you for your research and opinion Dave.

      Off the cuff, I’d say yes, all iPhone 4’s will have the same problem until Apple changes something. But it does seem that only American’s (AT&T users) are experiencing the problem, and then not all users.

      The obvious reason would be that AT&T’s network is lousy. The problem only shows up (we expect) when the signal is weak. By analogy, NZ Telecom users would have more of a problem than those on “the other network”.

      My suspicion is that spectrum (frequency) allocation also has something to do with it. To understand that properly I’d have to do a frequency analysis. I’ll see if the motivation arises!

    What, pray tell, is a ‘wit’ and how is it calculated?

    • Dave  On 12 July 2010 at 9:00 am

      A wit is a measure of signal strength in dB relative to the minimum signal level required to maintain the connection. Taking that level as nominally -113 dBm, then:

      signal level (wits) = signal level (dBm) + 113

      Using wits moves the scale of signal strength so that it reads like a speedometer, from zero to 60 (say), instead of from -113 to -53.
