Apple's annual developer conference in San Francisco.
iPhone Vulnerability, Fix Coming on November 21st in Firmware 2.2?
SIT reports that they notified Apple of the issue a month ago and that a fix will become available on November 21st through a firmware upgrade.
This seems to confirm an earlier report that we would see iPhone Firmware 2.2 released on that date. The iPhone 2.2 firmware contains a number of small new features we have previously detailed.
