Various tweets and blog posts from developers who tried -- and failed -- to snap up Worldwide Developer's Conference (WWDC) tickets in the scant two minutes they were available from Apple this morning indicate that the company is contacting some of those turned away to offer some tickets to the event. The "second chance" calls are unlikely to be made to all developers, and so the company has already announced that videos of all the sessions will be made available to registered developers as the conference progresses.
