The second-generation iPhone is easily the hottest device of the summer, though connectivity issues are now softening the hype.  A number of buyers worldwide have been complaining about 3G-specific connectivity problems, including spotty reception and dropped calls.

Now, Apple appears to be addressing the problem through a firmware update, without publicly admitting the issue.  The company recently issued the upgrade - OS 2.0.2 - while reservedly pointed to a 'bug fix' release.  Just recently, reports suggested that the connection issues were linked to a chip from Infineon, though neither company has confirmed the cause.

The firmware update is automatically triggered during an iTunes sync.
