5 Megapixel iPhone?

It’s far from an official announcement, but sources online are whispering that the update to the iPhone will bump the resolution of the device’s camera to 3.5 megapixels, and if that wasn’t a step in the right direction, it goes on to say that there will also be a 5-megapixel camera which is on its way from Apple, and should also see the light of day before the year is out. What do you think? Rumor or leak?
