Skyfire's iPhone app, which allows users to play Flash video on their iOS device, has been temporarily pulled from the App Store amidst overwhelming demand.

Skyfire said the app is now "sold out" and is not currently available for purchase.

"Skyfire has historically generated high demand for its browser products but nothing like this," Skyfire chief executive Jeffrey Glueck said in a statement. "It was hard to predict consumer demand since this was our first paid app, but we were blown away by the demand and sales."

Skyfire Web Browser for iPhone hit the App Store on Wednesday afternoon, and the $2.99 app quickly shot up the list of top paid apps in the store. Soon after, Skyfire tweeted that it was an "incredible launch day" but that "some videos may not play or [will] play intermittently." It said at the time that it was expanding capacity.

That's what PCMag encountered when we on an iPhone 4 over 3G. Videos either timed out or loaded and produced jittery results. Editor Lance Ulanoff tried it out on an iPad over Wi-Fi and had better results.

By day's end, however, users reported that the Skyfire app was no longer in the App Store. Had Apple cracked down on the app? Had it malfunctioned?

"The outage has nothing to do with Apple, the app is still approved," a Skyfire spokesman said in an e-mail. The popularity of the app, however, quickly overwhelmed Skyfire, and the company decided to temporarily stop "accepting new purchases."

"The company is working to increase capacity and will be accepting new purchases from the Apple App Store soon," Skyfire said, though it did not elaborate.

The app is designed as a full-fledged Web browser and includes an address bar, Google search box, and popular trending search terms. Navigate to a Web site that includes Flash video and, in theory, the Skyfire app will display that video in the small screen on the bottom menu, or "SkyBar." Tap the video and Skyfire will convert Flash to HTML5 and play it on your screen.
