Update: Looks like current iPhone owners will have to wait until July 11 to upgrade to firmware version 2.0 and access the iPhone Application Store after all. Word was that the store would open for business as early as June 27. Turns out that report was false. The good news is, a survey of iPhone app developers indicated that 70% percent of all applications will be made available for free. Not bad!

Piper Jaffray's Gene Munster uncovered a real thriller here. According to The Unofficial Apple Weblog, he surveyed application developers just after Steve Jobs' keynote on Monday. Just over 70% of respondents said they'd be offering iPhone and iPod Touch applications for free. What's more, apps that do require payments will likely cost under $3. This is incredible news. People who were worried about seeing applications cost $10 or more appear to have nothing to worry about.

On top of this, many of the developers said that they will be building enterprise-level applications. What those apps will be weren't revealed by Munster's survey, but the news bodes well for the iPhone's future as an enterprise-class device.
