iPhone OS 4.0 will be released in less than a month?This article contains unofficial information.
OK, let´s get it together and stay calm. We already reported the OS version was actually alive and kicking back in December last year, although we still don´t really believe we will see it this soon. Moreover, March 14 is Sunday and it´s not that we don´t like this particular day or something, but we highly doubt it that Apple would actually bother announcing the new OS on that day, because you know, even He rests on the seventh day of the week.
