Almost as soon as the iPad was shown in Steve Jobs’ hands back in late January, speculation ran rampant about whether or not some of the stock iPhone applications were missing in action, or simply consolidated into some kind of secret “widget mode.”

MacRumors is letting the air out of the so-called “secret widget mode,” a theory that missing iPhone applications have been included on the iPad, revealed only by way of some kind of Mac OS X Dashboard-style magic (with a five-finger gesture being proposed). Among the missing apps are Stocks, Weather, Voice Memo, Clock and Calculator.

But according to Daring Fireball’s John Gruber, his sources dispute that there’s any kind of “secret widget mode” and that the missing apps were in fact scrapped by Apple CEO Steve Jobs.

“It’s not that Apple couldn't just create bigger versions of these apps and have them run on the iPad,” Gruber writes. “It wasn't a technical problem, it was a design problem. There were, internally to Apple (of course), versions of these apps (or least some of them) with upscaled iPad-sized graphics, but otherwise the same UI and layout as the iPhone versions.

“Ends up that just blowing up iPhone apps to fill the iPad screen looks and feels weird, even if you use higher-resolution graphics so that nothing looks pixelated,” Gruber continues. “So they were scrapped by you-know-who. Perhaps they'll appear on the iPad in some re-imagined form this summer with OS 4.0, but when the iPad ships next month, there won't be versions of these apps. At least that's the story I've heard from a few well-informed little birdies.”

Furthermore, Gruber notes that while iPhone games will work well on the iPad, simpler “non-game iPhone applications” may feel strange on the new device, regardless of which method they are run (blown up to full screen or at native resolution as a small box in the center of the screen).

It seems like the iPad will be an entirely new user experience, which will likely require a lot more app tweaking to make enhanced versions of existing apps work well. We’ll all know soon enough, as the Wi-Fi enabled iPad will finally be available on April 3…
