iPhone5 will by released in mid-August

A job posting put on an employment website targeted towards job seekers in the United Kingdom, Reed, has stirred rumors that the iPhone 5 could be released earlier than the tech community had originally thought. The iPhone, which was expected to be released in September of this year, may actually come out a little bit earlier than expected, in mid-August

The job posting that started this rumor is in search of "full-time iPhone Sales Staff for an exciting project to work 5 days a week (Tuesday-Saturday) for the period 16th August - 29th October within key retail stores". The post, which was put out by Gekko Ltd a staffing firm in the UK, shows up several different sections of the site, with each one for a different area of Great Britton. Gekko has previously been employed to do retail hiring for Apple in the past, though it has mostly been in the Apple sections of larger stores and not in the actual Apple stores themselves.

The posting implies that Apple believes that they will have a need for more sales staff during this period, which some people have taken to mean that they have a big launch on tap for that week.
Of course, since this is all speculation and Apple is not big on giving out information about the release of products before the day of the launch only time will tell if the speculation is true or not and an August launch would be a welcome surprise for end users that have been salivating over the idea of a iPhone 5 for months.
