Earlier today, one of the developers behind iPhone game The Impossible Test let us know that he had observed evidence of three unreleased iPhone OS versions (4.0, 4.0.1, and 4.1) in his application's Pinch Media analytics. The news has drawn a bit of attention today, especially in light of today's announcement from Apple regarding an iPhone OS 4.0 preview event later this week, and Engadget was able to obtain a screenshot of the Pinch Media data.
iPhone OS 4.0 was noted in Pinch Media analytics as long ago as last December, but mention of 4.0.1 and 4.1 versions appears to be new.
One issue is that operating system version numbers are relatively easy to fake on jailbroken devices, casting a significant amount of doubt on this report and causing us to post it to Page 2 simply for interest and discussion. Such information would be more reliable if it could be linked to Apple-owned IP addresses, but we have no indication that that is the case with this report.
