I’m slightly loathed to publish this story because the information lies somewhere between total speculation and the bleeding obvious. Stay with me here, you’ll see what I mean.

So, word has it via iPhone Buzz that OmniVision has won the contract to supply Apple with the CMOS sensors for the iPhone of next Tuesday.

They’re saying that it’ll bring the iPhone 3.0 handset up to 3.2-megapixels and, beyond that, they’re taking consignment of 5-megapixel equipment for a second handset later this year.

So, it’s total speculation because none of this has been confirmed with anyone, and it’s the bleeding obvious as the camera is the one place on the iPhone that’s simply been screaming to be upgraded ever since the first handset came out two years ago.

As for a fourth iPhone, well, it’s possible Apple plans on doing to their phone range what they’ve done with iPods and, indeed, we’ve heard murmurs about it already but my money’s on 2010 for that kind of action. Perhaps this other optic set up is for another piece of Appleware. Tablet anyone?
